PV Gap

Tony Said:

Cost of installing solar panels?

We Answered:

These numbers don't look realistic, but this is an accounting problem, no a real-life one.

NPV of the $11k paid = $11k (cash)

It would be more realistic to assume that the person would pay their electric bill every month, and save 1/12 of that $3000 each time. It would also be more realistic to assume that the saved dollars would grow with inflation. However, the problem seems to be set up for fixed annual savings of $3000. So the NPV of $3k, saved after 1 year, is 3000/(1+0.072) = 2798.51 . The NPV of the second $3k is 3000/(1.072)^2 = 2610.55 . And so on, for 6 years, just add up each year's contribution.

The NPV of the $9k recovered when the house is sold, presumably because a buyer would pay more for a house with panels and lower energy costs, is 9000/(1.072)^6 = , etc.

Andy Said:

anyone know of a solar panel distributor?

I'm not sure where you live but if you live in California, Arizona or Nevada you could call Sungate Energy Solutions. They give free home energy analysis' and quotes. You can call 888-9Sungate.

Looking to install automatic gate opener. Retrofit an existing sliding (not swinging) gate. Need references?

We Answered:

You should jump on that bid, it's dirt cheap.
2 man days work to set the forms, pour the concrete, and run the conduit.
1 day to install the gate and align the sensors.
1 day to connect the whole system and verify the operation.
All of this plus the materials and a profit makes the $3100 a very low price. Get a 1 year parts and labor warranty.
