  • whole home Solar
  • Anybody on the Board have any direct experience with using solar to generate electricity for you house?
    Thinking of installing solar just to cut down on my electric bills. Got plenty of sunshine in my neck of Texas!
    Any advice would be appreciated.
    Thanks,
    Bob

  • I use 12 volts as a back up. The battery is always connected to a tender plugged in to 120 volts. Or and later, I will use a solar panel to charge the battery.
    I will use only about three 12 volt LED lights. The stove and non ducted furnace will be propane. I will also have three in the wall 120 volt heaters. The hot water heater will be an on demand propane. The water heater and furnace can be fired with 12 volts. I will also have a water tank and a 12 volt pump. All of this is so I can stay warm, and have hot water for the next time the power goes off. My well pump needs 220 volts, so the generator can not power it. If the power stays off for too long, we run out of gas. I will also have about 1100 gallons of water in outside tanks. Gravity can fill a bucket to get water, or I may use a 12 volt pump.
    The above is all being worked on at the moment as I am building the new mansion on my Island. It will be around 775 square feet on two floors. Later i will build a 12 X 14 mansion expansion, and that is where the wood burning stove will go. Plus all the junk that will not fit in the main house. Like the washer and dryer.

  • We looked into that.
    We had talkedd to other people that had it installed.
    We asked them actuall how long did it take to pay for itself.
    They were said the seller told them it wwould take 7 years to pay for itslf
    but they said it took 11 years to do so. The outfit we talked to was Capital.
    They wanted $24,000 to install it.
    I asked the salesman how long it would take to pay for itself.
    He said 7 years, I asked if they were bonded, He acted like I threw a buckit of
    cold water on him. We did not sighn at that time and we never heard from them again.
    So be warey of what they tell you.

  • It reminds me of the story of the elderly lady that had solar panels installed. She missed the 1st, 2nd, and 3rd payments. A representative from the company came to inquire why she had missed 3 payments, her response was....PAYMENTS? the salesman said it would pay for it self.

  • Most of the solar salesmen I have spoken to around here give a guesstimate of 5 years, except one person who said he calculated about 8 years! He was even willing to give us all the panel and inverter models, so we could do a proper comparison.
    Everything my research shows is that his pricing is very fair, and we will probably go with him.
    But I appreciate all the input I can get!
    Thanks,
    Bob

  • I would look what you have spent per year for the last 3 years and make an average.
    If you spend $300 per month, that is the most you can save which is $3600 per year less your monthly connection fee.(the cost of having electrical service per month/year). If that is $100 per month then you really can only save $200 per month or $2400 per year. If you spend $30,000 to install solar, divided by $2400 you get 12.5 years to pay back. You would also have a cost of 3% interest on $30,000 that you spent and do not get. You also need to consider the cost of maintenance and or any breakdowns.
    I have not been able to find a system that has less then a 10 year payback in actuality.
    I designed and installed a system that runs lights and TV's and computers, basically everything other then the refrigerators, water heater, and furnace. It works well, but still needs backup if it is cloudy for three days in a row. I am currently expanding the system to run a heat pump so I can heat and cool the first floor of our house.
    The hardest part is backup power and the cost of having to stay connected to the grid. Also, the batteries are more expensive every year.
    The Tesla Powerwall looks like the best system I have seen.
