Reliable clean solar energy solutions from Matthew Wrist Coventry UK: Is solar power really expensive? This is probably the most debatable aspect on the entire solar energy pros and cons list. The driving forces behind the development of solar energy are rooted in politics. Solar power is incentivized to compete against other energy sources on the market. On the other hand, the U.K. government, similarly to the rest of the world, provides incentives to every major energy production market – not just solar.

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 systems generally don’t require a lot of maintenance. You only need to keep them relatively clean, so cleaning them a couple of times per year will do the job. If in doubt, you can always rely on specialised cleaning companies, which offer this service from around £25-£35. Most reliable solar panel manufacturers offer 20-25 years warranty. Also, as there are no moving parts, there is no wear and tear. The inverter is usually the only part that needs to changed after 5-10 years because it is continuously working to convert solar energy into electricity (solar PV) and heat (solar thermal). Apart from the inverter, the cables also need maintenance to ensure your solar power system runs at maximum efficiency. So, after covering the initial cost of the solar system, you can expect very little spending on maintenance and repair work.
Best clean solar energy tech news with Mathew 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.
A 4kW solar panel system is a common size for the average Warwickshire UK home. It has an output of 3,400 kWh per year and costs around £6,000. If you compare this to the average annual electricity consumption of a household, which is around 3,200-4,100 kWh, solar panels can cover 83-106% of your electricity demand in perfect conditions. However, this depends on sunshine hours and energy usage. A more detailed breakdown of seasonality and monthly energy output can be found further below. In addition, with incentives like the Smart Export Guarantee (SEG), you can even earn money for surplus energy exported back to the grid!
A phenomenon known as the ‘albedo effect’ causes solar panels to be highly effective even in snowy climates. The white colour of the snow actually reflects sunlight, therefore, more electricity can be produced — the same way skiers and snowboarders can get easily sunburnt on the pistes. Naturally, the snow needs to be cleared off the solar panels first in order for the system to work. If your panels are covered by anything, it will reduce their efficiency. A typical commercial solar module has an efficiency rating of 15-20%. One important challenge of the PV industry is to improve solar module efficiency, and at the same time, keep down the cost per cell. Naturally, there are many factors that can affect the efficiency of your solar panels, from the type of solar panel to angling, and seasonality.
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).
