peterfranks Posted August 19, 2022 Share Posted August 19, 2022 Apologies of this is a stupid question. My roof is only 18°, as I use high quality imported clay tiles with double lock etc, which according to the manufacturer brochure have been tested and proven watertight at 17°. Would you think it is possible to replace the tiles with solar panels, and make it waterproof? Link to comment Share on other sites More sharing options...

Not replace the tiles , just get the right mounting system . https://www.lazada.co.th/products/cpac-solar-mounting-i2149586530.html?spm=a2o4m.searchlist.list.11.1c396f05YgxJn6 https://www.lazada.co.th/products/cpac-solar-mounting-i3365338956.html?spm=a2o4m.searchlist.list.13.1c396f05YgxJn6 https://www.lazada.co.th/products/psi-solar-cell-rail-mounting-i3538421834-s13202715717.html? https://www.lazada.co.th/products/solar-cell-tile-roof-hook-i3226792818-s12020723114.html?

How much usable average wh per month could i expect from 6600w panels? Could i calculate from your numbers, or your different setup will make it different? Battery limits not counted for now.

More capacity will be added if PEA come along with electronic meters. 2 1 3 Link to comment Share on other sites More sharing options...
Popular Post Crossy Posted September 30, 2022 Author Popular Post Share Posted September 30, 2022 Here we go with the September numbers, a pretty crumby month overall, not helped by the hybrid being out of service from the 22nd leaving us at about 6kWP of active panels. 3 1 Link to comment Share on other sites More sharing options...

Small development nearby just finished building and about eight new houses over there all have brand new digital meters. Anyone considering solar do consider there is a good chance you will not be feeding back to the grid, especially if it's a new build. 4 1 Link to comment Share on other sites More sharing options...

Thx for this. We were thinking of switching our PEA Supply to a 30/100 from 15/45 to support a "hide-away/man cave" in the back of the property but those plans are on hold because of the weather. Maybe after reading your comment, I guess this plan will be cancelled if it means that we will get a Digital Meter. Running it on Solar (off-grid) will be out of the question because of the Massive cost involved, Aircons, Pumps etc etc running. (Need to spend more on the Solar install then the cost of building the "man cave". ) 1 Link to comment Share on other sites More sharing options...

I would definitely avoid changing meters, but a 15/45 will power an awful lot, it won't just explode at 46A ???? With the solar helping it along I'd expect it to be just fine. 1 1 Link to comment Share on other sites More sharing options...

Muhendis Posted October 13, 2022 Share Posted October 13, 2022 I am curious to know how all this grid feedback works with regards to inverter protection. What protective device do you have between the output of the inverter and the grid? RCBO, MCB, nothing? 1 Link to comment Share on other sites More sharing options...
Crossy Posted October 13, 2022 Author Share Posted October 13, 2022 Each inverter has a regular RCBO at the board. It "should" really be a Type-B (which isn't blinded by DC over 6mA) same as is supposed to be used for EV chargers, but finding them here is somewhat ... Everything has good, solid grounds of course.

Well, a little more up to date research reveals the availability of Type-B RCDs e.g. https://www.lazada.co.th/products/rccb-type-b-ev-car-2p-c-4p-32a-40a-i3112938453-s11534562001.html? Note that these are RCDs and so require a separate MCB for over-current protection.

Popular Post Crossy Posted December 31, 2022 Author Popular Post Share Posted December 31, 2022 Happy New Year everyone! Let's see what 2023 has in store. Meanwhile, the generation numbers for December are in. Over the past week or so we've been generating more than we've used (cool weather = no A/C and it's been nice and sunny) so our "Monthly Energy" has been on a downwards trend. Must ensure we don't actually go negative! Blue = Total consumption Green = Solar generation Red = PEA usage. 2 4 Link to comment Share on other sites More sharing options...
Popular Post Crossy Posted January 1, 2023 Author Popular Post Share Posted January 1, 2023 And for an annual perspective (thanks @KhunLA for the idea). Averaged over the year we generated 84.46% of our electricity needs from fusion power. EDIT Over the year we totalled 10,897kWh from solar, at 4.5 Baht per kWh that's 49,000 Baht I've not paid to PEA. Madam is happy ???? EDIT 2 I've not updated my ROI spreadsheet for a while so I got a nice surprise when I punched in the numbers to date. We are just under a year from break-even and truly free energy ???? 5 1 2 1 Link to comment Share on other sites More sharing options...
