I am new here. I am going to install a new system in my home. I Live in the Azores in the Saint Jorge island. The Azorean government has program for solar systems with 100% support in money. My application was accepted (a lot of documentation was necessary) , which consists of Goodwe gw5048d-es and 12 solar panels Hyundai 485 watts. My house has on side of the roof facing sunrise and the other sunset which is not optimal. I am going to put 6 panels on each side making two strings in total. Each side will have two rows with 3 panels each, one above the other. My question: Should I leave a space between the rows or not, with a space its better for maintenance? But her in Azores the wind sometimes is very strong and the panels together maybe better. Hope someone can help. Sorry for my bad English.

Welcome Paulo, that's quite amazing, you have made me want to move to the Azores 😀 Looks like they have given you some decent kit there.

That's not too bad as you have 2 mppts on the inverter so it just means you'll get good energy earlier in the morning and later in the afternoon which will give you a better spread of energy throughout the day and might be better if you are running batteryless.

If the wind is very strong then maybe a bit of space between the panels might be a good idea so the wind can escape through the gaps and the panels don't act as a big sail. The roof mounting brackets I have seen usually leave a little gap between the panels anyway for the brackets to attach. Also, depending on your bird life there you may need to get to the panels to clean them from time to time.

I've attached a document on solar panel installation that you might find helpful.

Thanks Jumper for your help. For me to be eligible to receive the 100% of money there are many  norms. I pay for 6.6kw power from electricity company, I can not have more than 6.6 kw of solar power. I have to prove I dont have any dept with the government. Have to send last 6 electricity bills. Send last IRS documentation and more.

The Government is thinking of a new project to buy batterys for solar with 85% of the cost. If this comes out I will also be candidate do buy some pylontech .

Ola Paulo, Bom dia.

Yeah, sounds like the usual government hoops to jump through, but I'm sure they need to be very careful supplying such expensive equipment to the public. If they had a program like that in this country there would suddenly be truckloads of new equipment available on the black market.

Welcome! Looks great!

I think is only in Azores not in the mainland. The government has 19 million euros to spend in 4 years on this project. This is also for companys but the only receive 60%. I can send you the internet page but its in Portuguese: https://portaldaenergia.azores.gov.pt/portal/PRR/Solenerge?portalid=0.

 

Paulo, obrigado pela a imformacao. very interesting indeed, From what I read you will be exporting to the grid the excess power. I know that Azores islands are almost self-sufficient green power.

the Azores currently generate about 40% of their electricity from renewables, 60% of which come from geothermal energy (the remainder is provided mainly through wind and hydroelectric power).

Because i will receive money from the government I am not allowed to sell excess to the electricity company.   WHY, the government is owner of 51% of the electricity company.

What I will use for the excess is the FREEDS. I have a solar water heater which has an electric element( I never used), the element will work with freeds. When there is excess electricity , it is sent to the element in the water tank. Freeds communicates via wifi with a shelly(with clamps) to know if i am exporting to the grid.  I will put some photos o my solar water heater and freeds. On the display is the watts consumed from the grid (769watts). When I finish my installation and have excess the display will go negative (-).(-). I bought the board from  https://www.tindie.com/products/bugrovs2012/pwm-16a-3500w-triac-leading-edge-dimmer-50hz-60hz/.
