A household rooftop solar panel system can reduce pollution by 100 tons of CO2 carbon dioxide in its lifetime—and this includes the energy it took to manufacture the solar panels.4 Solar panels can improve future air quality for humans as well as the millions of birds, fish, and mammals that are negatively affected by pollution each year.
Solar Energy For Your Home Secrets: How To Get Renewable Energy Using These 5 TechniquesAny discussion regarding the effectiveness of solar power and its efficiency should first of all be qualified by the fact that we're talking here about a technology that is in its relative infancy and is improving all the time.That having been said, it's fair to say that, while massive improvements have been made in the overall efficiency of solar panels, there's still a long way to go.Let's take a look at how solar panels work and get some background as to why this is and what can be done to improve solar panel efficiency.The Secret's In The CellThe solar cell is the basic building block of a solar panel and is where all the action takes place as far as the conversion of sunlight into electricity is concerned. A cell consists of a negative and a positive silicon wafer, which work together in reaction to the sunlight striking them to cause electrons to literally jump out of the wafers to create a DC (Direct Current) electrical circuit. This is known as the photovoltaic (PV) effect.So, even with the best will in the world, 100% efficiency is simply not achievable. Certain techniques are being used to improve cell efficiency, such as reducing reflection loss through surface structuring, or stacked (or tandem) cells, or concentrator cells, so there's plenty of room for optimism for the future efficiency of cells.But, even with the restrictions on the potential efficiency of solar cells, the fact that we're able to produce usable electricity from such an unlimited source of energy as the sun is nothing less than miraculous in and of itself. Add to that the fact that this is clean, renewable energy with no carbon emissions or harmful effects that can reduce and potentially help eliminate our dependence on dangerous fossil fuels and it's clear that solar is a wonderful and effective technology whose time has come.
The Ultimate Home Solar System ChecklistEliminate or significantly reduce your electric bill with solar energy
One of the biggest reasons to go solar is that you can eliminate or significantly reduce your electric bill. An average monthly electric bill of $100 becomes an annual $1,200 expense. Over 20 years, that same $100 monthly bill balloons to $24,000 paid to your utility, and that’s before factoring in electricity rate increases that will likely make your 20-year energy costs even higher. Installing a solar panel system at your home or business takes you out of this cycle.
What You Need to Do Today About Home Solar SystemFrom the residential consumer’s point of view, there are mostly pros when it comes to switching to solar. If the consumer is adding solar while still having access to the grid electricity, I don’t really see a con, unless the cost of the solar system is prohibitive and financing is not available.
First of all, the consumer gets almost free energy after the paying for the solar energy system, so you start saving on the electricity bills. Depending on the cost of the system, the payment is recovered from these savings over a certain period of time. That time depends on the initial cost, any financing costs, maintenance costs and price of the energy the consumer is saving. In most cases, the cost of a solar water heater or a PV system could be recovered in 5-10 years.
The time could be smaller if any government incentives (tax credits etc.) are available. A solar system increases the value of the house also. On top of that, the consumer has the satisfaction that he/she is contributing to a cleaner environment. One additional advantage we have seen as a consumer using a solar water heater is that it comes with a large storage tank.
If one member of the family takes a long shower, the others don’t have to wait for the water to heat up before taking a shower. This is the main reason we have had a solar water heater on every home we have owned since 1979.
How To Get The Great Deals On Solar PanelsSolar industry involves many different activities, from production of the crystalline silicon or thin films to the construction and operation of PV solar plants. This article maps the value chain of solar industry and explains how different segments relate to each other.The Basics of Value ChainsThe concept of value chain was first introduced by business scholar Michael Porter, famous for his research on competitiveness and strategy. As early as in 1985, Porter described value chains as a tool for strategic analysis, based on the processual view of organizations. According to Cambridge University’s Institute for Manufacturing, the idea is to seea manufacturing (or service) organization as a system, made up of subsystems each with inputs, transformation processes and outputs. Inputs, transformation processes, and outputs involve the acquisition and consumption of resources — money, labour, materials, equipment, buildings, land, administration and management. How value chain activities are carried out determines costs and affects profits,Porter’s value chain approach (firm level). Picture credit: WikipediaPorter’s model can be applied at various scales: firm-, region- or industry-level. At the industry level, the value chain encompasses all the various processes involved in the production of goods or services, from raw materials to the delivered product, and is based on the notion of value-added at each stage of production. The British geographer Garry Gereffi developed this idea further with his concept of the Global Value Chains, that span across different regions of the world. According to Gereffi, global value chains include multiple firms and multiple locations, and allow to describethe full range of activities that firms and workers do to bring a product/good or service from its conception to its end use and beyond. This includes activities such as design, production, marketing, distribution and support to the final consumer.Both tools can be of great help in analysing such global industries as solar photovoltaics. They allow to understand the geographical distribution of different production activities, their interconnections and dependencies, and ultimately aid decision-making in choosing new markets for expansion.Photovoltaics Value ChainThe value chain in photovoltaics is considerably complex, and involves all the different processes required to create a utility-scale PV solar system. First, raw silicon must be produced, purified, cut into wafers, doped, cleaned and coated. The cells formed this way are subsequently assembled into modules, arrays and then combined with electrical components to construct a full-fledged system. We have written in detail about these processes before. Now it is time to take a look at the bigger picture.Picture credit: https://www.linkedin.com/pulse/machine-learning-from-fundmental-capabilities-features-ravi-muluguSolar DAO uses crystalline silicon solar panels, which is more complex than thin film panels. The latter’s value chain is much shorter: the models are manufactured in one single step from raw silicon and other compound materials by deposing the photovoltaic material on glass or plastic. On the other hand, in concentrating photovoltaics the value chain is more complex than in the case of crystalline silicon, and involves higher costs, because silicon or thin film solar cells must be combined with optical concentrating systems, coolers and trackers, before it can be assembled into an array. That’s why crystalline silicon cells are better suitable for utility scale PV solar plants.However, the real journey starts once the solar cells and modules have been produced. The manufacturing process captures only the upstream part of the value chain, while most of the activities happen in its downstream part. It involves the project planning, implementation, and use phases.Picture credit: Green Rhino Energy, http://www.greenrhinoenergy.com/The project planning phase is very important, and we have written about it before. It encompasses area planning, system preparation, operational model, applying for approvals for the use of land, and considering different financial options. Once this has been done, comes the implementation phase, in which the actual construction process takes place, the system is getting verified and installed. The last part of the downstream value chain is the use phase, which involves a complex socio-technical configuration, as the researchers from Finland’s Aalto University warn. What they call socio-technical configuration involves operation and maintenance activities, as well as different adjustments and negotiations regarding the property relations around the PV solar plant, its positioning within the industry and the market, negotiations with local authorities and communities, and how the plant will be operated, and the energy it produces will be distributed and used, in a given local social context. In terms of the project planning, the use phase involves consideration of political and country risks.

Thus, the following players must be active on the market:Suppliers of the manufacturing equipmentSuppliers of the raw materials for wafer-, cells- and module productionProducers of crystalline siliconProducers of silicon wafers and ingotsProducers of PV cells and modulesProducers of the mounting structures and trackersProducers of electrical componentsSoftware suppliers for monitoring system and operation of PV solar plantsIn terms of services, there are financial, legal, consulting and testing services that go through the whole value chain, as these services may be required at each stage. One can also include different activities such as education and training of the personnel, publishing and PR efforts to promote solar energy, as well as government relations services to obtain approvals, subsidies and support grants. When it comes to actual phases of the value chain, there are several necessary services as well:Wholesale distributionProject planning and developmentDesign, engineering, and constructionOperations and Maintenance servicesIn an ideal market environment, all these activities can be performed by different organizations that enter contractual relations with each other. In reality, however, firms tend to optimize their cost structures by reducing the transaction costs. There are several ways of doing so: they can form a cluster, by concentrating related and interdependent activities in one region (for example, silicon, wafer and modules production), vertically integrate, by including different stages of manufacturing or downstream activities into the firm structure, or diversify their processes, that is, for example, being both a distributor and doing some activities in unrelated businesses.Depending on the age of the firm and different competitive factors, in can be a pure player in the solar energy industry, or it can be more diversified: for example, like big fossil fuels corporations that enter the renewable energy field as a separate business activity. Diversification can also be organized in terms of combining different fields of renewable energy, like solar and wind.The other trade-off that the firms face is the one between different degrees of vertical integration. Today, most companies are partially vertically integrated, but none covers the whole value chain, although there are many highly specialized companies in the upstream (manufacturing) and downstream (services) parts of the value chain.Thus, the whole value chain can be depicted as follows:Picture credit: Green Rhino Energy, http://www.greenrhinoenergy.com/Read our next post about the geography of solar photovoltaics.

Solar Power for the Common HomeownersPV Panels and Maintenance
PV panels need little maintenance; they just need to be kept respectively clean and to not be overshadowed by trees. If dust or snow becomes an issue, they need to be cleaned with warm water and a brush, or high pressure hose. If you don't feel like doing it yourself, you can always contact a window cleaning company and they will do the work.
PV panels are likely to last up to 35 years or more, but the inverter needs to be replaced after ten to fifteen years. However, it is always good to play it safe and check with your installer, what are the specific maintenance requirements for your system, as well as its respective insurance.
Solar photovoltaic electricity is an excellent source of renewable energy and there are plenty of reasons why you should start taking advantage of the benefits it brings. In addition to reducing your carbon footprint, you will also cut down on your electricity bills. What’s more, PV panels are easy to maintain and will last for a long time.
Step-by-Step Guide to Bargain SolarInteresting California Solar Fact:
Apart from the pollution given off during panel manufacturing, solar power produces no pollution, which is a by-product of non-renewable energy consumption and one of the biggest global killers.3 Pollution affects as many people as HIV or malaria and has serious effects on children, older adults, and all living plants and animals.
Just A Quick Tip About SolarSo our goal was to cover virtually allof our energy utility cost by solar energy. We looked at covering only asmaller percentage and we looked at covering the a greater percentage and inthe end we decided that we wanted to try and cover almost all of our energyconsumption. So our original energy utilization reviews, we came up with anumber of approximately at least 85% would be covered, but since we have kidsmoving out of the house and we're moving into the empty nest, then we will probablycover everything, which will be good. So my name is Charlie and I was the projectmanager for this installation. This is a residential installation in the suburbsof Mechanicsburg. So this is a 73 kW system, it's about 225 panels. One of thereasons we settled on the system size is it's the maximum residential size wewere allowed to install by the utility in this area. I would say the mainmotivation for the switch was just a desire to be more ecologically consciouswith all of the issues with global warming and using fossil fuels, this was always adirection we wanted to move. So paradise worked with us to try and minimize theimpact by locating the panels towards the back of our property as far out of the sightline as possible. At the beginning part of our project we went back and forth anumber of times with the layout of the solar panels, the percentage of energy wewent to try and cover, what our goals were and they came up with a number ofalternative strategies and arrays that we eventually settled on the optimaldesign. So there's a lot of communication back and forth at the beginning of the projectin the planning stages. The construction phase took a little over two weeks. Wehad a couple stops and starts because of the weather. This was springtime so wesaw everything, we saw some heavy rains, we saw some snow storms and then we sawsome good sunny days. So when we had the sunny days we really tried to put thehammer down and get as much done as possible. Paradise Energy made the whole project veryseemless how coordinate with a fence company and then pretty muchinstallation went as expected. I would recommend Paradise Energy Solutions forpeople that want to explore a solar energy alternative because they wereeasy to communicate with and came up with a number of different strategieswith us to meet our goals. People should know that Paradise Energy is a companythat will find the right solution for what they want to do with solar and willnot try to sell them something that won't help them achieve their goals.
5 Things You Need to Know About Solar PanelsAdding solar panels to your home can increase your property value more than a complete kitchen remodel.
Aside from all the great environmental benefits of going solar, there’s also a very real monetary incentive to do so. Installing 5kW of solar panels can increase the value of your home by up to $29,555 or more, depending on solar panel production.
Meanwhile, according to the folks over at HGTV, a $15,000 kitchen renovation is likely to return 92.9 percent of the cost at resale, for a total of $28,935.
And this doesn’t even begin to account for the savings you’ll likely receive on your monthly electricity bill. With Sunrun you can save 20% on your electric bill—which could amount to $20,000 over the life of your system.
Just A Quick Tip About Solar
Excess energy can be stored in battery systems.
Fact: If you are living on the grid, your system is connected to the electricity grid, thus you would benefit from a net metering system. Additionally, if you are connected to the grid, you are still able to keep your current local utility company, so if you produce more electricity on some days, you end up having more electricity credited to your own account.
Therefore, if you need more electricity at night when the system isn’t running, you end up using the extra electricity produced to power your home directly from the grid. This is done automatically so you won’t notice any changes when the switch occurs whilst still have a low electricity bill.
Large Residential Solar QuestionsSolar Energy and Solar Power
Solar Energy needs to be transformed to solar power and then it can be used for heating or electricity. There are two main methods to convert solar energy to power.
Direct or photovoltaic (PV) - The conversion is done through solar panels and the generated power is used for electricity.
Indirect or solar thermal - The conversion is done through solar thermal collectors and the generated power is used for heating.
