CoolPV-Proof of Performance, Wow!

In addition to the recent comment from a customer “My pool is 90 degrees, I can just jump right in!” CoolPV also greatly boosts electricity generation by transferring panel heat to the pool, thereby cooling the panels.

Sound too good to be true?  I wondered that myself.  However, in looking at the graphic below, you can see exactly where the pool water circulation turns on– we know it turns on at 12:30.  (We do this to maximize output during the PG&E peak afternoon rates.  This maximizes the financial return of the system, buy low sell high!)

If you look at the red dashed line, this is what we would expect the afternoon curve to look like, essentially a mirror image of the morning curve.  Instead the curve “flattens out” when the pool heat turns on.  So, the area between the red dashed line and the green line is all extra production that’s been enabled by the symbiotic relationship of pool heating and solar energy generation.  I’m nothing short of impressed, and neither are our customers.

Is solar right for me?

This is a good question, and one everyone should ask themselves.  In fact, we really don’t want to sell it to you if its not an investment we’d make ourselves.  We routinely see 15-20% returns on the systems we install.  This is a nearly unmatched investment return.  In this post I’ll try to summarize as briefly as I can an answer to this question.

PG&E customers: This one is actually easy.  I can tell you the answer is YES, no question.  I can tell you this without even seeing your bills.  Even PG&E’s lowest tier is still more expensive than to produce yourself with solar.  If I were a PG&E customer I wouldn’t hesitate to move forward with solar.  We can offset up to 100% of your usage and every kilowatt produced will generate savings.

SMUD customers: Here is answer is a maybe.  SMUD’s lowest tier today is about the same cost as generating the electricity yourself.  The higher tiers are more expensive.  So, sometimes we aim to simply offset the higher tiers rather than the entire bill.  SMUD requires a little more analysis, but we are happy to help explain the financials in easy to understand terms.

Here’s the good news: you don’t have to take our word for it.  Below we provide tools from both PG&E and SMUD to help you model savings for your particular usage.  Again, we are happy to assist you with this determination, but we just like to provide you with the tools to help make you comfortable with your decision.

Why buying is so much better than leasing

We almost always recommend buying vs. leasing solar.  It’s important that you know the difference.  Here are a few key points that demonstrate the advantage of owning.  We’ll show you exactly how much more you can save with a purchase over a lease.

  • With a purchase you receive the tax credit.  With a lease, the leasing company keeps the credit.
  • A lease decreases your savings.  The whole reason leases exist is because they are wildly profitable to the companies offering them.  Buy your system with cash or a loan and you keep all the savings.
  • Leases discourage buyers of your home.  An owned system is an asset to your home value.  A lease is actually a liability!  Most buyers know this, and its very common for real estate agents to point this out to their buyers.
  • Let us look at any lease proposal you have received and we’ll show you how much more you can save in an easy to understand format with no financing gimmicks.
