An estimated 100 million refrigerators, internet modems, and laptops are running mostly on fossil fuel for 24 hours every day in the USA. That adds 33 billion pounds of CO2 to the atmosphere every year. Here is a useful link to the Greenhouse Gas Equivalencies Calculator from EPA.

But there is something you can do to reduce this number significantly by just using one solar panel. Click on the above image to see the project poster in full detail. The numbers are based on our year long study. Daily average energy production in southern California for one regular sized (63” x 79”) solar panel:

1.44m2 (panel surface)
x 6kWh/m2
 (average solar radiation in LA per day)
x 0.17 
(panel efficiency)
x 0.75 
(overall system efficiency)

= 1.1kWh per day (equivalent of 0.577 pounds of CO2 per day or 210 pounds per year)

The cost factor for a resident in Los Angeles on a Time-Of-Use (TOU) meter are:

$0.26/kWh (average rate on tier 2 with SCE)
x 1.1kWh savings per day 
x 356 

= $104 savings per year

The proposed concept will not need any permits from local utility providers because it is a hybrid off-grid system that you can assemble yourself. You can gain independence form the grid and prevent blackouts for your most important household items.

We are currently working hard to make mass production of the Solar UPS Controller a reality, and will start a crowd funding project in the near future.  Once we can mass-produce this unit, you too can have a hybrid off-grid solar system for less than $900, while decreasing your carbon footprint and saving money too!

    That’s a great concept. People should really go solar. It’s much easier than before, even dyi projects are not that hard to do, and apps are available like this one EasySolar , which helps in the design of pv system, does the calculations, shadowing simulations, etc., everything along with a financial analysis. Solar panels are great investment!
