Sustainable and reliable clean energy solutions by Mathew Wrist Warwickshire UK: Because of shading, insufficient space and ownership issues many American homes are simply unfit for solar panels. With the introduction of shared solar, homeowners can subscribe to “community solar gardens”, and generate solar electricity without actually having solar panels on their own rooftops. The advantage of this is that installation costs can be cheaper if large numbers of panels are installed on vacant land. Legislation is required to enable community solar in each state and whilst this has existed from some time in some smaller states it is only just coming into play in key states such as California and New York.

Usually the largest single cost factor is lighting. Obsolete light bulbs only use about ten percent of the electricity to make light. 90 percent are lost as heat. They produce heat rather than light, because they are based on a glowing filament made of tungsten. Modern LEDs use almost all of the electricity to make light. You can clearly notice this from the fact that they stay cool, i.e. there is much less loss. A good LED needs about a tenth of the electricity to produce the same amount of light. And because it does not heat up so much, it lasts much longer. And: The price of LEDs has come down so much, that exchanging them for regular light bulbs pays off within one or two years. The same is true for industrial lighting systems which often use mercury vapour lamps. These, too, use up a lot of electricity and can easily be replaced by LEDs.
Although pollution related to solar energy systems is far less compared to other sources of energy, solar energy can be associated with pollution. Transportation and installation of solar systems have been associated with the emission of greenhouse gases. There are also some toxic materials and hazardous products used during the manufacturing process of solar photovoltaics, which can indirectly affect the environment. Nevertheless, solar energy pollutes far less than other alternative energy sources.
Latest clean solar energy tech news with Matthew Wrist Leamington UK: Those appliances in the household with the highest electricity demand are the dish washer, the washing machine, the tumble dryer and the kitchen stove. These can easily be equipped with timer switches, so that they run during the day, when the solar generator on the roof is producing a lot of output, which can be used directly. A high-wattage stove might be a challenge for PV by itself. In this case, a large storage unit (solar battery) can be used as a buffer for short-term load peaks. Because it is not just the number of kilowatt hours on the roof that has to be sufficient, but also the currents made available at short notice. This determines if a storage unit is designed for capacity (in kilowatt hours) or output (in kilowatts).
Solar panels take advantage of one of nature’s most powerful yet free resources: the energy produced by the sun. Solar panels, also known as photovoltaic systems, use semiconductor technology to convert energy from sunlight into electricity that can power your household for free. On average, more than 4,000 solar panels are installed in Coventry UK each month. Many homeowners want to make the transition to renewable energy by investing in solar panels. They are a great option that can not only reduce your energy bills but also help you earn money from the surplus electricity generated.
A 4kW solar panel system would require approximately 16 solar panels with a 250W power output, while a 5kW system comprises 20 solar panels. The first step is to identify your current energy consumption. You measure this in kilowatt hours (kWh), and it’s important to take the time needed to calculate this as accurately as possible. Check your electricity bills to get your power consumption (in kWh). You can either calculate month by month or add your monthly/quarterly consumption together for an annual figure. Decide on how much of your electricity bills you want to cover with your solar panels — this can be anything from 10-100%. Your decision will affect the system size and costs. Calculate how many solar panels actually fit your roof. An average solar panel takes about 1.44 m2 of roof space. Don’t forget to include at least 30cm from the roof’s edge. Adjust the system size if you realise that you don’t have enough space for all the panels you calculated.
So just what is the best generator for home use? It depends on your situation. For example, the best standby generator for home use isn’t necessarily the same as the best generator for running your off grid home. And the best generator for an off grid cabin depends on the length and frequency of the run times. It also depends on whether your off grid cabin has any other energy source (ie. solar panels or a windmill.) And how much power your home systems require. When you’re reading the specs on a generator, look for any manufacturer’s recommendations on whether it’s for occasional use, emergency use, or to use off the grid. Not all generators are made to withstand the heavy use of an off grid home. So don’t make the off grid homeowner mistake of choosing one labeled “emergency use” as your everyday power backup for solar panels in the low-sunlight days of winter. Doing so could void the manufacturer’s warranty.
