Solar batteries win against generators every time.

Many of our inquiries from Tampa and Orlando residents, wonder which is the better investment, a solar battery array or a generator?

While there may be a lot of confusion around this topic, the data is clear that in the war of battery vs generator, a solar battery system is the more efficient way to store your solar power vs a backup generator.

Here are just some of the results and ways the Enphase Battery Power Storage System is the clear winner.

NOTE - This is an actual building site with REAL beta testing done right here in Tampa Bay, Florida. Actual costs and performances are used.

Let the battle begin!

SOLAR BATTERY CASE STUDY OVERVIEW: Tampa Bay, 2020

The leading brand 20KW generator was used. $16,000.00 average investment cost w/ a 500 Gallon LP tank buried in the ground. Extended Warranty is a typical $1300.00 extra.

Study Time Frame:

One week without power, 7 days or 168 hours per year minimum. LP fueled with a 500 Gallon (this gives 5-8 days of power, depending on load 50 to 100%). A 500-gallon tank can hold 450 gallons supply in the ground or 400 above ground. The in-ground is used for this study. 450 supply /2.39 usage @ 50% Load /24 hours= 7.8 days / 7.8 days x 24 hours = 187 hours.

Maintenance recommended:

Required every 100 hours and or once a year. For this study, we will use 2 services. Average cost $150.00 each. (Costs may be less if you do the service your self due to unavailable service technicians.)

Generator Fuel Cost - $4 per gallon

Delivered to Spring Hill, FL June 2019/ Usage per hour is 2.39 gallons at 50% load. 2.39 x 187 hours = 445 Gallons of LP consumed. 445 gallons at current cost $4.00 = $1,780.00 Fuel cost $1,780.00 Fuel cost + $300.00 servicing =$2,080.00 Total cost for 7.8 days without power. Operating 50% load.

What does all this mean regarding the best backup power source?

Simply put, in the battle of Enphase batteries VS generators, Enphase wins, hands down. 

You have the strongest warranty, silent operation, the Florida solar tax credit, and of course the peace of mind that you will not have to concern yourself with fuel delivery, or maintenance on your system.
