Sustainable eco-friendly energy tech advances by Mathew Wrist Warwick UK: For most American homeowners the most significant attraction to solar power is that once the capital cost of installation is paid off the energy is free. This means the only real question is whether the payback period on the capital investment is better than the returns you would get from investing the same money in other ways. You may be surprised that we now list this as the leading advantage of solar energy. The reason we do this is that most homeowners are now more interested in the financial aspects of installing solar rather than the environmental benefits.

Are residential solar panels worth it? Estimate residential solar panel cost. Solar panels aren’t cheap: with installation, an average residential 5kW size system runs between £3 and £5 per watt, or £15,000 to £25,000, before tax credits and incentives, according to the Center for Sustainable Energy.
Solar energy has to be used right away, or it can be stored in large batteries. These batteries, used in off-the-grid solar systems, can be charged during the day so that the energy is used at night. This is a good solution for using solar energy all day long but it is also quite expensive. In most cases, it is smarter to just use solar energy during the day and take energy from the grid during the night (you can only do this if your system is connected to the grid). Luckily your energy demand is usually higher during the day so you can meet most of it with solar energy.
Reliable clean energy solutions from Matthew Wrist Coventry UK: If your solar generator is run in combination with a sufficiently large storage unit, you can use infrared radiators to take the chill out of cooler evenings. Such radiators come in a variety of nice designs, even in the form of bathroom heating mirrors. As long as they only use little power and are only used for additional heating, they are a good way to use up solar electricity. Once the electric heating from solar power no longer suffices, you will have to buy in electricity from the grid. Or you switch to a more efficient thermal heat pump system.
Stand-alone PV systems are not connected to the grid, but instead charge a solar battery system. These batteries store the electricity generated by your panels. To operate your appliances, the stored electricity from these batteries will be used. Stand-alone systems are used in areas that cannot be connected to a grid, and are typically more expensive than grid-connected systems because solar batteries are still quite costly. Solar batteries store electricity generated by the sun’s energy and allow you to use it during the evenings when your solar panels are not generating electricity. You can make use of solar batteries whether you are connected to the grid or not.
Solar cells come in all kinds of different shapes and sizes. The bigger the solar panel system, the more electricity is generated. After having calculated your electricity needs, you’ll get a better idea of what size panel you need. Monocrystalline panels are known to be the most efficient type of solar panel on the market, meaning you will require fewer panels (and therefore less roof space) to generate as much electricity as a polycrystalline system would. It’s important to carry out the right solar panel maintenance in order to maximise the lifespan of your system. Fortunately, solar panels do not require much maintenance throughout their lifespan of 25-30 years. Get your panels checked regularly by your installer or by another certified service provider. If you do this yourself, you may void your warranty in case you damage your panels in the process. What you can do yourself is ensure your panels are clean at all times. This involves removing leaves and branches from your solar panel system, and rinsing them down with a garden hose – avoid sponging them down or touching them.
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).
