Skipalongcassidy Posted June 22, 2023 Share Posted June 22, 2023 I am looking to find and contact Chiang Mai local contractors for quote on a whole house hybrid solar system... any and all referrals appreciated. Link to comment Share on other sites More sharing options...
Crossy Posted June 22, 2023 Share Posted June 22, 2023 If you don't score here in the local forum, drop me a PM and we can move to the Alternative Energy forum where more solar users will see the thread. Have you done any consumption measurements to determine just how much solar and how much storage you would need? Useful as a baseline, even if you intend getting your contractor to size the system. As a starting point I suggest reading your meter at 9AM and 5PM every day for a week or two. That would give you a day/night consumption figure. The night consumption will allow you to size your batteries. 2 Link to comment Share on other sites More sharing options...

koosdeboer Posted June 23, 2023 Share Posted June 23, 2023 I am very happy with North Solar Rooftop. They come from Lampang but installed many solar systems in Chiang Mai. Good advice, good after service and good price. They have installed a solar system in my house and were very flexible with my extra wishes. https://l.facebook.com/l.php?u=https%3A%2F%2Fnsr-solar.com%2F%3Ffbclid%3DIwAR2pnObKhgMk0eeYGCDCw4SyQHyWYwfFJIgDWSVgsbfSw1BBHUil3Oi8nWM&h=AT2eY057RhLC6d2oh_TglUUwIocxZ2yWYyweoBiVbyIG0zlLfdgsNqSkWg1n8ZHoaPIJSYVTp7Zlp3nCVkaWa248roWDPWGwy6RRzKGGGk0d0d92S4-sNTcPsqsdZv75Z16sSw Phone number for an english speaking technician 0850905458, name Chon Link to comment Share on other sites More sharing options...

Yorkshire Tea Posted June 23, 2023 Share Posted June 23, 2023 The advertised prices for installation I've seen are a complete ripoff. Seems the best way to go is DIY or buy the components yourself & find competent electrition/handyman to do the install for you. Any suggestions for the latter around Chiang Mai?

Dellboy218 Posted June 27, 2023 Share Posted June 27, 2023 You can try eyekandi solar in Hangdong, they are on Facebook. Link to comment Share on other sites More sharing options...
Skipalongcassidy Posted June 28, 2023 Author Share Posted June 28, 2023 Thanks for all of the replies... I am finding that solar is very expensive in Thailand compared to the USA... Not only is the equipment expensive but the installation labor is ridiculously high... to top it off the Thai gov't and electric companies do not want you to be solar Independent... their buy rate is extremely low and is non existent if you add batteries to the mix... where most of the world is offering incentives to go solar, Thailand is not.

TimeMachine Posted June 28, 2023 Share Posted June 28, 2023 First step. Check usage, cost, and workout payback period. Think you'll find a 20 year payback period for an average 5kw ish system. It's just not worth it. I installed one small system that has no batteries. Just works during sunshine. Used a hivolt inverter(4kbht) that takes the 10 panel (45kbht) 400 v and uses that to go to 240ac. My decision wasn't based on saving money but just as a one time hobby project in Thailand for my partners mother. It's enough to run fridge TV AC fans rice cooker during sun times. Reverts to street power at night via a mixing board. I would not recommend solar for any other reason than just because of hobbying with electronics. Solar systems are too expensive in Thailand. There is no government support worth mentioning about. You are just adding more equipment that can fail. The pro of saving money is just not there. Sure it sounds cool and all but not worth it money wise. But for a hobby and interests sake. Go for it. And Of course if no street power at your area then you have no choice but to do it. 1 1 Link to comment Share on other sites More sharing options...

Depends where & who is selling the system. I priced our system vs USA (Philly tri-state area) and USA was 2-3X more expensive. Will agree, no incentive here/TH, quite the opposite, and if ever getting buy back, quite the silly low rate. Powers in charge, still not ready to give up their grip on controlling the energy supply in TH. Edited June 28, 2023 by KhunLA Link to comment Share on other sites More sharing options...
McTavish Posted July 2, 2023 Share Posted July 2, 2023 ~ 6 year payback for my 10kw/3phase/hybrid system installed. (no Li battery just yet) Eyekandy was OTT with their pricing, nice gear, but .... Huawei 3kw (no battery) system installed by TNS costs 189,000 and would suit most folk Link to comment Share on other sites More sharing options...

System @ 240,000 /72 = 3,333bt per month on daytime consumption with pool/irrigation pumps + house. (doesn't allow for non productive cloudy days) With 5kw LiFePo battery payback = 6.75 years Link to comment Share on other sites More sharing options...
patman30 Posted July 2, 2023 Share Posted July 2, 2023 (edited) i would suggest you figure out exactly what you want before contacting any company the installation is expensive if they have experience with solar dont be sold a cheap system make sure you know what brands you want or will accept i imported my batteries as could not find decent here FYI, felicity solar the company i bought from now have a BKK office so shipping is quick, inveters and batteries how many units are you currently using, whats your monthly bill? when do you use electric the most? for hybrid you have 2 options, max out panels/inverter and spin back the grid meter as much as possible in day (not advised) or spend less on panels/inverter and add a battery you can add battery upto about 5-6x the PV i just added an extra battery to my setup, have 3 x 5kw inverters with 60kw battery but i am offgrid so you could put a 3kw inverter with upto a 15kw battery, which would likely be about ideal for battery longevity Edited July 2, 2023 by patman30 Link to comment Share on other sites More sharing options...

Are you saying you are paying 3000 baht less a month now for power? Link to comment Share on other sites More sharing options...

Most sensible advice thank you. Our house is unoccupied during daylight hours. We have a family friend electrician who charges us 300 baht labour per day (we always give him several times that of course). Even with 2 baht per unit Feed In Tariff it doesn't make sense for us. My house in UK has a completely free 'Rent a Roof' PV installation which gives me unrestricted daytime use. Overall, a one-third reduction in my electricity bills. Feed in Tariff not payable to me of course. Edited July 2, 2023 by The Fugitive Link to comment Share on other sites More sharing options...
