Solar Power Battery System Cost

If you re going solar with a grid tied solar system it s worth considering battery backup as well.

Solar power battery system cost.

Grid tied systems are often the easiest and most cost efficient type of solar system to install. The amount of energy stored in the battery the amount of wattage used by the appliances and electronics connected to the battery. That averages out to around 660 800 per kwh. The life of the battery storage system will vary depending on a number of factors including but not limited to.

Solar system with battery backup. Solar batteries range from 5 000 to 7 000 and from 400 dollars per kilowatt hour kwh to 750 kwh. The average solar panel payback period is 7 to 12 years and solar energy saves 600 to 2 000 per year on electricity costs. The installed cost of a battery is closer to 11 000 to 18 000 and 800 kwh to 1 300 kwh.

Their main drawback is that when the grid goes down ul requirements mean grid tie systems shut down immediately. But as a starting point the price of solar battery storage starts at 5000 or around 105 a month over 5 years for a smaller enphase system while larger batteries such as tesla powerwallstart at around 12 500 14 000 depending on a number of factors. Note that these prices are only for the battery itself not for the cost of installation or additional necessary equipment. As a general guide a battery system will cost between 800 to 1200 per kwh installed.

The average cost to install solar panels is from 10 626 to 26 460 after tax credit for a 6kw to 12kw system to power an entire house. However a quality battery for residential solar energy storage can cost up to 7 000 or more. Small solar batteries run between 200 and 2 000. For example the tesla powerwall 2 with 13 2kwh of storage capacity will cost around 14 000 fully installed while the 9 8kwh lg chem resu h battery is closer to 9000 plus the extra cost of a compatible hybrid inverter and installation.
