High quality solar panel supplier? 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.
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.

How much does a single solar panel cost? At the time of this writing, the installed cost of solar panels was between $7-$9 per watt: A 5 kW system would cost around $25,000-$35,000. Many utility companies offer incentives, and some subsidize as much as 50% of system costs.
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.
