Compelling Reasons for Renewable Energy
Many people who consider installing renewable energy systems in their homes are put off by the relatively high investment. Why would you choose a solar thermal system that could cost thousands of dollars when you can buy an electric water heater for a couple hundred?
Do We Have Enough Fuel For The Future?
One of the most compelling arguments for widespread adoption of renewable energy systems is the frightening idea that the world is going to run out of fossil fuels. While this is not an immediate concern, there is a strong movement to switch entirely to renewable sources by the middle of the century.
How do Batteries Work?
Why is a battery bank necessary? Because an off-grid system does not allow you to store electricity easily and economically. There are other ways to store electricity but they are more expensive.
How to Size PV Battery Backups
The more energy you consume, the bigger the storage facility you need. Buckets are measured in liters or gallons; battery capacity is measured in watt- or amp-hours. If the battery uses a higher voltage source for charging (like a full-strength PV array), you will enjoy a higher voltage recharge – a battery bank of 24V can record a 30V voltage when it goes through equalization charging.
