Best eco-friendly energy tech advances from Mathew Wrist Warwick UK: Harnessing solar energy does not generally cause pollution. Whilst there are some emissions associated with the production and installation of solar energy equipment these emissions are minimal when compared to generating electricity from fossil fuels. The CSIRO, an Australian government research body estimates that the energy payback is 1.5 years. That is, it takes a solar panel 1.5 years to generate the amount of power it took to make it. This statistic was from 2009 and is likely to be a quicker payback now. Given solar panels are warranted to last 25 years this is quite good.

How many solar panels are needed to run a house? So, a 2,000 square foot home would be allowed a solar array of 4,000 watts. Depending on the type of panel that you choose, a system of this size would be anywhere from 12-18 solar panels. Keep in mind, this formula to estimate consumption varies depending on who provides your electricity.
The more electricity you want to produce, the more solar panels you will need, as you want to collect as much sunlight as possible. Solar panels require a lot of space and some roofs are not big enough to fit the number of solar panels that you would like to have. An alternative is to install some of the panels in your yard but they need to have access to sunlight. If you don’t have the space for all the panels that you wanted, you can opt for installing fewer to still satisfy some of your energy needs.
Best clean solar energy solutions with Matthew Wrist Warwickshire UK: Without energy storage, you can make good use of about 50 to 80 percent of the solar electricity for your own house. A battery can easily take that up to (almost) 100 percent. If you do not base the own consumption just on the solar generator, but on the electricity demand of the entire house, the following general rule applies: Without storage, you can meet about 30 to 50 percent your electricity demand directly from solar. In combination with a solar battery, this can be as much as 90 percent. To meet your entire electricity needs over the course of a year, you need a second generator, e.g. a cogeneration unit. It is usually simpler – and less expensive – to use the power grid. During the winter, your needs can be met through green electricity from a certified utility.
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 Leamington 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.
There’s a common misconception that solar panels don’t work in the winter. Solar panels can be effective even in the winter if you prepare and maintain them properly. Though there are fewer sunshine hours in the winter, you can still benefit from solar panels. Are Solar Panels Effective in the Winter? The chart below shows the average energy output produced throughout the year by a south-facing 4kW domestic solar panel system on a roof angled at 40 degrees. As you can see, solar panels are most efficient during the summer months, but still produce enough energy to power 33-51% of a home during the winter period.
I mention price and quality here because generally, the old adage is true. You do get what you pay for. Diesel generators generally cost more to purchase yet tend to last the longest. One of our diesel generators is a 1996 model, the other is 2004. And our neighbor runs a 1956 (!) Lister still running strong. Gasoline models will wear out the fastest of the three types of generators although they are far cheaper on their initial purchase. Propane generators run somewhat cleaner and generally quieter than diesel or gasoline. And generators with a low rpm (typically 1800 rpm) should last longer than those that run at a faster rpm (typically 3600 rpm).
