People decide to buy photovoltaic systems for a variety of reasons. Some want to help preserve the Earth's finite fossil-fuel resources and reduce air pollution. Others want to invest in an energy-producing improvement for their property. Some people like the security of reducing the amount of electricity they buy from their utility, thus making them less vulnerable to future energy price increases.
Installing solar PV systems not only reduces your electric bill but it also increases the value of your home. Panel pricing coupled with today's state and federal rebates and tax credits make going solar even more affordable. And utilizing alternative energy to meet your power needs is critical to not only reducing your dependence on non-renewable energy sources, such as fossil fuels, but to also have a direct and positive effect on our environment.
Here in Arizona, the earlier in the year that you install your system, the more the financial benefit to your annual energy costs. This is because the sunny and cool weather in the winter enables the highest PV production, and thereby allows you to bank the most kWh for use during the hot summer months.
