A charge controller is a great addition to any solar array, specifically those that are working above 10 watts on a regular basis. These small devices act as "ON" and "OFF" switches to protect your batteries. They prevent overcharging from damaging your batteries and can provide more advanced charging options depending on the make and model.
If you own your own business, consider installing solar panels to your building. This will help cut your overhead expenses. Solar energy can power your computers, lighting and other office equipment. Additionally, business owners can get tax breaks for installing energy saving green products such as solar panels and solar hot water heaters.
Track numbers when getting solar panels for the home. Solar panels might not be a good option if you cannot count on optimal exposure to sun rays in your area or if you use more power than a regular solar energy system can generate. You need to do all your homework, so you know if this type of energy is really going to save you money.
Cars that operate on solar power can cut down on carbon emissions a lot, but this system is not perfect yet. Having said that, small power machines that run on solar energy are available. Solar powered generators can be purchased, and are a great source of energy in emergencies.
