Solar energy systems come with multiple warranties that apply to different parts of the installation, and trying to keep track of them all can get confusing. Here’s a simple guide to the different warranties for your solar energy system, and which ones you should really pay attention to.
For residential electricity users who want to control and master their electrical consumption, as well as business owners and agricultural users, a hybrid approach offers the best of both worlds: reduced or even eliminated utility charges and backup during critical times, without the need to stay totally off the grid with a system that can draw from the grid when necessary to make up the difference.
Your solar panels’ lifespan is long enough to produce decades of renewable energy for your home. Additionally, solar panel recycling options mean that once your system does finally reach the end of its life, you can be confident that your panels won’t end up in a landfill.
If you’re shopping for a solar-energy system, one of your first questions is probably, “How much will it cost?” Reviewing prices for a 5-kilowatt (kW) system is a great place to start — that’s the average system size in the United States.
A friend of mine participated in the Second-Annual State of the Electric Utility survey. He also shared with me the results of the 2014 survey, which tabulates the opinions of more than 500 electric-utility professionals on the subjects of demand growth, distributed generation, power supply, regulatory models, and a number of other electricity-generation, transmission, and distribution-related issues.
We all know that renewable energy is an important part of a greener, more sustainable future, but are there health risks associated with home-scale photovoltaic installations? The jury is still out in the world of industry-sponsored and independent research, but there is a fast-growing segment of the population who feels ill from our ever-increasing use of electricity and wireless frequencies.
Installing a home solar energy system is a smart financial investment for many homeowners. As you evaluate offers from solar companies, there are many different factors to consider – the equipment that you choose for your system, your financing options, and the installer that you select all have an impact on your solar savings.
Installing solar panels for your home is becoming more and more affordable.
