Didn't they just announce in the last couple days they shut the solar purchase program down or will quite shortly for new applicants due to safety reasons? The article was in bankkok post this week

Would like to share some info/experience on how to get hold of a Power Purchase Agreement [PPA] with PEA to sell electricity to them.

 

The online system is called Power Producer Information System [PPIM] and one of the programs is to buy electricity from small households.

Hope this helps. Will keep you posted on the progress. If you are familiar with this program, please share.

========

 

A few years ago I installed a small DIY on-grid system [ 3.3kw inverter, 2,000 Wp panels ].

As my production was equal to what I used, I did not bother to look into the details how to make a contract to sell electricity to PEA. 

 

This month I extended the system to the full capacity of the inverter. On a normal sunny day I can export/sell around 10kwh per day.

With the current 2.2 baht / kwh price and a contract of 10 years I can earn max around 70,000 baht.

 

After some searching I found on the PEA site the online process to submit a request to have a PEA selling contract.

It is called PPIM for rooftop solar households, type 1 residential.

Please check your PEA invoice, column Type, if you can apply.

Fee to submit the request is 2,000 baht excl VAT.

 

After scrolling thru the online form I learned that I cannot do it on my own.

I need a certified engineer that will sign off the electrical diagram [Single Line Diagram] of the system.

 

So I called a few installation companies in Prachuap, where I live.

One gave a quote of 15,000 baht + 2,500 baht extra, because they did not install my system. 

 

After providing them some pictures of the combiner box I had a call with sales.

Success rate of a PEA selling contract is 100%. No rejections sofar. However I would be their first DIY customer.

Wait time PEA for the whole process is 3 to 6 months.

 

A few weeks ago, a company from Ayuthaya installed a solar system at my neighbour's roof.

I managed to ask the onsite engineer to check my combiner box.

 

After 20 minutes checking he said: AC circuit breaker of inverter in main panel should be 32A instead of 16A.

And the earth/ground cable should be black color instead of yellow/green.

Hmm. I thought that yellow/green was the international standard for ground.

 

Accidentally my Thai wife found an engineer thru her friend. He also happen to live in the same town in Prachuap.

He came to see the system. He also explained the request process, as he also installs solar systems.

 

Nothing wrong with my system! No changes needed. What a relief.

 

After submitting the form with many attachments e.g. SLD diagram, PEA will take 45 days to come with an answer.

For Prachuap customers the process is centralized at PEA Phetchaburi.

 

Progress of status of the request can be checked online.

If approved for the next step, print out the online documents and pay the fee of 2,000 baht at your PEA office.

 

PEA will make an appointment for inspection of around 3 hours.

They will check the combiner box, main house panel, inverter and the earth bonding stick into the soil.

They will not go to the roof to check the grounding of the panels.

 

After PEA inspection, it takes an additional 30 days before final approval can be expected and that the selling/export is registered by PEA systems.

So a total of around 3-4 months. The engineer also told me that there is no waiting queue for export meters in Prachuap.

 

The best part came at the end. He will not charge us anything, except for expenses. As long as we can do some marketing about his solar installation business.

Are you running a few air conditioners?  I think that's our biggest expense along with our pool pump.

 

I'm kicking myself for not installing solar!

The wheels grind oh so slowly ...

 

Your neighbour still hasn't got his "sell" meter (unless he has a two-dial analogue unit). Hope he doesn't get caught out spinning it backwards.

 

Despite having everything in place and "approved" for an export meter @Thaifish got caught out by the meter reader and had a no-reverse meter installed. AFAIK he still hasn't got his export meter :sad:

Let's pop this over to the Alternative Energy forum.

 

Good news that you've managed to at least start the process with a DIY system, the acid test will be actually getting your export meter, at least one member has been waiting years for his (On a professionally installed and approved system)!

 

Shelling out around 20k for approval to sell at 2.2Baht per unit, so you need to sell 9,000 units to break even on the approval cost. If you are really over-producing by 10kWh per day that's 900 days or 2.5 years.

 

Do keep us informed how things pan out and good luck! ???? 

 

In my view, at this point in time, and due to the approval processes, it almost seems like SHEER STUPIDITY to waste time on the process to sell to the power company.

 

At least, sheer stupidity, compared to selling the electric power to a neighbor for Bt.3.0 per kWh.

 

Or, why not just offer to recharge your neighbors' EVs for Bt.3.0 per kWh?

Seems easier and more profitable,...

At least, to me it does.

 

Maybe I have not yet thought this through, however...

 

(Why does one need the power company to act as a middleman? Nobody likes to pay commissions.)

@sathornlover

 well, never a boring time in Thailand ;). May I ask which PEA province this is? 

 

When we visited the PEA desk to ask about how the billing and crediting would occur, they said we had a choice of 2 [debit & credit separately] or 1 aggregated monthly bill.

 

Have you checked the PEA smart app? There you can see your monthly bills. I don't know if they will report credit bills as well.

here's a quick update on the payment of the surplus amount, I didn't address the strange meter discrepancy that is now being discussed in this thread:  “Apparent discrepancy between metering systems” during our current visit.

 

After our first unsuccessful appearance at PEA, we tried for the second time this week. This time at least we were lucky. Instead of dealing with a clueless representative, this time we were lucky enough to actually get in touch with the employee responsible, who was able to give us more reliable information. But some of this information was even more unpleasant. For example, we were told that in the event of a longer stay abroad, we would have to send an authorized representative who would have to appear every month. When my wife intervened, they at least agreed that this could be discussed in the team, whether this would be possible only every two or three months, although we came with all the necessary documents, the payment process for the first and second electricity bill could now take place, but we would not have received the money until the 16th at the earliest, i.e. ten days later. Which would then require another visit.

 

So of course we asked for the money to be transferred to an account. Of course, we had a copy of the bank book with us, but it turned out that there was only one bank that could be used for this, namely the PEA's house bank Krungthai. So we had no choice but to march off again and reopen a bank account with Krung Thai, of all banks, just for this purpose, which from my memory is one of the worst and I therefore closed it after a short time.

 

We then gave the PEA authority a copy of the requested new bank book for each payment in the afternoon. This had to be handwritten on each one, stating "that the account holder agrees that the amount will be transferred to this account" + signature of course ;-). The transfer itself will then take another week ...
