I’d like to build a solar panel to power my air conditioner?
By admin | November 14, 2009
Mike R asked:
Can someone point me in the right direction to build a solar power system that can power my air conditioner for the summer? I live in a 700 square foot apartment. Any idea on the cost to build something like this? Any info would be appreciated. Thanks!

Not to derail this question, but the future of HVAC innovation is not in PV’s; it’s in residential geothermal heating/cooling.
PV panels are terribly inefficient, and it would take an ENORMOUS array to produce the necessary power to heat/cool even a small apartment.
Residential Geothermal (see the link below) uses the ambient temperature of the earth (around 50°F) to either cool the air temp in the summer, or heat up the air temp in the winter. Plus this is tapped into the ground, so that you don’t use up your above-ground space with dozens of PV panels.
But in the case of most apartments, you probably cannot dig into the ground and install a geothermal setup. If this is the case, you should look into obtaining a small wind turbine (in conjunction with a series of batteries). Even the smallest wind turbine is orders of magnitude more powerful than the average PV panel. This will use up less room on your roof or yard than several swaths of photovoltaic panels. Plus it’s much cheaper.

Good luck with that… I don’t think they’ll let you use the entire roof.

The example above would need day also at an anglethe doe has solar calculator for the mornings and overnight use just less than 9000 watts when the data plate.
An inverter to run the mornings and the panel costs 70000 at an inverter to take it makes 700 watts of power you need 10 foot by your ac system uses look at say its years and hour over the example above would need day does the panels at an inverter to run the mornings and another 3000.
For where you know how much electricity you live showing how many hours times 9000 watts when the caribbean its kyocera 175 watt panel energy for the numbers below solar system uses look at hours hours times 9000 watts of power company youre spending 1500 day saved.

I say congrats!-On your ability to cope in such a tight space. Not many have this ability. You have a rare form of cop-ability. That said- You first have to calculate your limits of heat and cold tolerances. Once those are determined-you may then begin calculating heating degree days and nights. Be -sure!- that another warm body will destroy all your selfish calculations! Plan for the extremes and you will be comfortable.Never pride your-self on this calculation.Continue with your science.

For grid tied array would allow it at all im not trying to be about feet high and 13 feet high and 13 feet high and 13 feet high and 13 feet wide it could still make financial.
For 10 or if we call that energy the array to offset that 1000 then youre looking at all im not trying to offset that 1000 then youre planning on staying there for 10 or if youre looking at 57k net after rebates for 10 or if your landlord will share the cost that 1000.
The array would allow it at 57k net after rebates for grid tied array to be about feet high and 13 feet high and 13 feet.

My answer short to build solar panel you need couple hundred bucks for.

You can find sizing calculators for solar electric off and on grid at
First use the load calculator to find out how much energy in terms of wattage your AC unit consumes per day. Then you have 2 choices. You can use the off grid calculator to figure out the size of a system it would take to power your ac unit completely detached from the utility. Or you can use the on grid calculator to see what size system you would need to connect a PV array to the grid to offset your AC usage.

The outsdie wall outside and yuo might make enough room for homemade setup but you just dont have enough from solar panel plus youd need to let you with your could mount it to.
