Thinking about going Solar.

[Mike Madison]

My electric rates are tiered, that is, the more you use, the higher the cost per kWh. So I put in a modest, (3.5kW) grid-tied solar system to knock of the expensive tiers. It's eleven years old now--no problems. Probably hasn't paid out yet, but it might eventually get to zero. In addition, I have an off-the-grid solar powered pump in a deep well. Five panels (1.4kw) run a DC pump, so there is no inverter, no batteries, etc. When the sun shines, it pumps water (about 20 gallons per minute). I use this for supplemental summertime irrigation in my orchards. That whole system (panels, pump, controls) only cost me $3700. It's worth it to me just to have a back-up supply of water when the power's out and my main well won't pump.

We had a 10kw system quoted to us. It came in after rebate of 22k. They wanted 4500 just to bury the cable which is ridiculous. We ended up not going this route even with the fact of knowing the tax credits will be done after this year. For solar energy to be connected to the grid you have to have a policy incase you back feed the grid. I believe ours was a million dollar liability. It was gonna cost an extra 250 dollars a year for the insurance. So keep that in mind. We live in the middle of 8 acre wooded lot and truth be told I didn't have time to take down trees for the project as shade is you enemy. They claimed that you get most of your power from the ours of 10am to 4pm or atleast thats what we were told. Id like to add solar but we might have to wait for a few years. It will be interesting to see how the solar companies will compete with out the tax credit. In all honesty they need to get more competitive. The tax credit has hindered the competition a bit. I had 4 quotes and off them were with in a thousand of each other. So they were all within reason.

This is a timely thread as my wife and I just signed a contract for a 20KW solar system to be on line sometime in November of this year. We are not going off grid but having done a great deal or research in the last five months, the numbers stack up favorably reducing our total utility cost from around $350.00 per month to something around $25.00. In as much as we have geothermal heating and cooling and electric hot water the +/-$25.00 covers 100% all utilities but for a small amount of propane used for the kitchen range and great room fireplace.
Buyer beware. We invited four company’s to bid on the project and the price spread between the four bidders exceeded 30K. We then eliminated the highest and lowest bidder and concentrated our focus on the two remaining bids checking references, financial stability, sight inspections of completed projects, and final delivered price.
What really makes solar viable is the 30% federal tax credit available until December 31,2018 and the allowable execellerated depreciation. Our break even point is projected at 9 years and with an estimated increase in electricity cost at 4% per year compounded the estimated utility savings over 25 years approach $100K.
To be continued as the project unfolds

Not to be a Debbie downer, but I think you forgot to offset your predicted savings by the money that could be earned alternatively if you invested the same money in something else. For instance $30k invested in an s&p fund averaging 8% a year, or better yet, a REIT stock paying 10% dividends. Compound that for 25 years time... that is unless you relish the idea of maintaining 25 Year old battery banks

We have been totally off-grid for 3 years now and I have no regrets. We bought the land knowing that there were no power lines within 10 miles. It’s not cheaper and never will be, but we wanted to be off-grid and didn’t mind paying the extra to do it. We don’t “sacrifice” but we do “manage”. We have a washer and dryer, dishwasher, microwave, toaster oven, and all the conveniences. Our walls are 26” logs and we have top grade double pane windows. THe majority of time we heat with the wood stove, which I can fill at 7PM and it will still be going strong at 7AM. We have a propane vented heater in the kitchen, bedroom, and bath, but rarely use them. Mostly they are for while we are away, when I set them for about 50 degrees to prevent pipes from freezing.
Stove, dryer, and water heater are propane, as well as the backup generator. We have a 3600 watt 48 volt system with twelve 235 panels and 16 Trojan L16RE batteries. The backup generator runs about 4-6 times in January when there’s snow or dark days and maybe once in June when the whole family shows up. Then there are hair dryers and such. We try to do laundry and vacuuming during the daylight hours to save on battery usage, but we don’t let it dictate what we do.
Overall we are extremely happy with the whole setup, but like I said, it is NOT saving us money. We have no electric bill, but when you amortize the batteries and equipment over the expected life, it costs more than being connected. But the peace of mind - knowing that if the grid goes down it wont affect us - it’s worth it to us.

Some things in life are not about getting rich, but doing what you feel is the best for you and your impact on this world. We are looking at solar to reduce our carbon footprint and reduce our fossil fuel dependencey.

I have given a lot of thought lately about going solar on my house, I haven稚 looked into it much but have heard of programs that will help so it痴 not as much money out of pocket.

Have any of you guys taken advantage of this? What痴 the pros and cons of solar?

I just feel like I want to invest into renewable energy when it makes sense to do so.

Ohio has done a very poor job of renewable energy, we are one of the highest non renewable consumer states in the country and have some of the poorest air quality and most polluted waterways in the country as well.

I currently live in a Net Zero house thanks to improved insulation, air sealing and minisplits, My 20 kW solar system provides all the power to heat & cool the house as well as keep an in ground pool at 90 degrees all summer. This is a 1988 modular ranch.

Every day I analyze customer electric bill both pre and post solar as I manage an engineering team that design solar PV systems. Together we have designed and installed over 5,000 systems ranging from a few kilowatts to 5 megawatts, both on and off grid.

Battery storage is becoming more viable every day.

We are building an off-grid home in the next couple of years in the CO mountains, so I am acutely aware of the current solar, thermal, wind, and hydro options. If you have specific questions please message me.

In general, I would only got off grid if I didn’t have easy access to the grid. If I had access to the grid, I would strongly consider a solar grid-tied system if you have high electric costs or if you are going to be living in your house long enough to offset the cost.

Wind really isn’t worth the cost vs solar. Hydro is just fine if you have the water and drop for it.

When considering off-grid, the first thing you must realize if you aren’t going to be able to live exactly like you did on grid. Identify major power draws and see what you can do without. House design is also critical. You have to understand solar-thermal properties and take advantage of each. You would preferrably build a new solar-thermal home with off grid, because you can do all of this right in the beginning.
Taking a home that is currently on grid and converting it to off grid would be very difficult. Environmental losses and all appliances are not made or designed for off grid use. No you dont need all DC appliances, but you do need to be smart about your AC choices and when you use them. For instance washing clothes when the sun is out just becomes a habit, not an inconvenience.

With off grid, you also need it professionally designed and installed by someone that has great experience with OFF grid systems. Not someone that does a bunch of grid-tied systems in the city and can do yours at a big discount. Off grid systems require careful engineering and planning to make them fully comparable to grid systems. You cant just throw in panels, an Inverter, a charge controller and some batteries and expect to get great performance.

Again if you have more specific questions please let me know. Best of Luck!

Darkblack, per my original post, we are not intending to be compleatly off grid and as such will not have any battery back up. Your point about alternative investment choices is sound and was a part of our solar consideration. As mentioned, my wife who is a retired financial consultant with New York Life Insurance, and I studied all aspects and cash flow consequences of a solar investment and concluded solar was a viable investment and would significantly reduce our occupancy cost given the historical fact that electric rates have risen at the rate of 4.5% per year and likely to continue to rise.
Our decision was not off the cuff, flash in the pan but carefully researched. A common comment by those interviewed currently using solar as a part of their enegery needs; “I wish I had made the decision years ago”.
Like any investment, your results may vary.

I can give you some data. I put in 9.2 kw grid tied system the end of '11. I got a good price on panels from my employer (Bosch - who dropped out of the business a few years later due to chinese competition) and also good prices on the inverter and racking system. The panels are not roof mounted due to trees, but since we had the land they are about 150' away in a clearing. In 6 years we paid off the investment (after fed and state credits), and also selling renewable energy credits (SRECs). The SRECs are bought to help states meet renewable energy credits. It was about $ 50/mwhr when we started, but today it averages $8/mwhr. ( SRECTrade | Home )

The system has been 100% reliable and produces about 60% of our energy consumption. We have net metering in our state, so this helps with the payback. House is 2800 sq-ft with 4 adults, 3 at home full time. He have geothermal heat/AC, all electric appliances, 2 refrigs and freezer, TVs, computers and other typical electric products. My bill is average $ 100/month over the year. Highest in the winter, lowest in the spring and fall.

I did the install myself (with help from some friends) and the only outside labor I paid for was an excavator to clear the land where the panels are located. I am not sure about the impact of tariffs, but I paid $ 1.92/watt for panels when I purchased, and I have seen prices around $ 1/watt or less for name brand panels today. Inverter prices have also dropped. For me it was a good investment providing low energy costs well into the future. I concur with others that companies selling no cash or lease programs are not worth it. If you have the money, buy it outright. If you are handy, do part or all of the install yourself to save money.

Amen to that. Am seriously considering a small solar system just to run the well pump, a computer, and some lights in case of power outages, which are fairly frequent here in the heavily wooded mountains. In this case it would be about convenience, not cost savings.

Thanks to all who are providing real-life solar experiences.
