Grid-Tie Solar Electricity
Many people speak longingly of having no electrical bill, that is being completely off the grid and self-sufficient. If you live in rural Alaska or high up in the Rocky Montains this wish might be a priority rather than a wistful thought. However, the systems - which include solar panels, batteries, converters and windmills - are complicated and fairly expensive. And for those who live near electricity going off the grid is a life-style change which, over the long run, would cost them way more money in both replacing parts of the system and maintenance costs. However there is a hybrid system that could give the best of both worlds.
A grid-tie system is a combination of the reliable grid connection and solar-powered electricity. This mix of technologies is directed into the main panel and cuts down on the electricity from traditional power sources. In a few regions - such as Tuscon, Arizona which has a Sunshare™ Program - this is a two-edged sword:
1) Saves money on the power bill
2) You can sell electricity back to the power company: If your power consumption from the solar panels is less than consumption the power company will buy it, giving you a credit on your bill.
Advantages:
1) No expensive, high-maintenance batteries and converters: The grid balances the peaks on a sunny day with the lows of night and either charges or credits you for the balance of electricity used .
2) Cost effective: This should be qualified with a “in the long run” notation. The system is not cheap but you slowly gain the upper hand after a few years as you do in a mortgage where, with each year, you begin paying down more of the principle. Since solar panels are guaranteed for 20-25 years and electricity will go up during that time your investment will be returned long before that.
3) No hassles: Unlike windmills and storage batteries there are no moving or deteriorating parts. Everything is hardwired to your electrical panel. (And remember the long warranty of the solar panels.
4) Increased home value: An installed grid-tie system is a major plus when selling your home. Who wouldn’t want a house with the ability to lower electrical bills?
