What is a renewable energy system? A renewable energy system uses sunlight, wind, and/or water to produce electricity to power your home. A basic system is comprised of four basic components: solar modules and/or wind generator, charge controller, batteries and an inverter. Energy is collected at the home site by the solar panels, wind generators, or hydro-electric generators and stored in batteries for later use. When you need electricity in your home, this stored power moves from the batteries through the inverter, which converts the power from DC to AC. Any DC or AC appliance can be run on an alternative energy system, including computers, televisions, and stereos.
What size solar electric system do I need to run my home? The recommended size of your system depends on your power consumption. If you want to completely replace your current electrical purchases from the utility with a solar electric system, the first step is to calculate your power requirements. To assist you with this process, we have designed an interactive sizing worksheet. If you design an energy efficient home, you can reduce your electricity usage dramatically. In the real world, the majority of home systems range from 2 kW to 4 kW. Where you live, whether or not you are on the grid or off the grid, and how you live will dictate the size of your system and its total cost.
How much does it cost? System size and cost are directly related to the number of appliances used and the length of time they are used. Simply put, the power collected must at least equal the power consumed. By analysis of the expected electrical loads, the experienced technicians at EV Solar can size the system to provide what the homeowner needs and can afford. This can be significantly less than the cost of providing a new line from the utility grid or continuously running a large generator. Beyond the initial cost of the system components, there are no monthly electric bills. You are eligible for a one-time Arizona State tax credit, Federal tax credit, and utility rebate (if within local, Arizona Public Service -APS- territory). The system will continue to pay for itself by providing reliable electrical service for many years. Please go to our list of Suggested Systems for pricing information.
How difficult is the system to install and manage? The new, state-of-the-art alternative energy systems are remarkably simple and reliable. Homeowners with average mechanical abilities can easily install and maintain their own systems. Based on 17 years of experience building and living in stand alone, energy independent homes, the professionals at EV Solar can also provide installation, maintenance and repair services. Generally, installation by EV technicians is calculated as 20% of the total cost of materials.
How long will my solar electric system last? Solar modules have been tested in controlled settings and in the field, with results showing module lifetimes in excess of 20 years. We sell panels manufactured by Shell Solar (formerly Siemens), which carry a 25 year warranty. Other system components have varied lifetimes. Batteries can last from 6 to 15 years, depending on care. The electronic components, being the most sensitive, will last anywhere from 3 to 20 years.
Can I use renewable power to pump water from a remote well? Self-contained remote power systems for well pumping and remote communications have long been a cost effective and reliable solution to a basic requirement. New advances in solar pumps have pushed the range of these energy efficient systems to even greater depths. State tax incentives and the offset savings on electrical infrastructure offer an added value. Careful analysis of the options available matched with the site conditions will provide the best return for your money. The solar professionals at EV Solar can help you do just that.
