TIL I learned about "integrated into the roof" solarpanel systems on a trade fair, which essentially replaces the existing roof tiles. Since we have to replace/renovate our roof anyway this summer, it seems like the perfect time to invest in such a system.
Together with a 10-13 kWh battery, we could reach a rate of self-sufficiency of 73%.
Yet, I heard that roof-integrated systems can heat up severely with potential danger to burn down the house. Does anyone have real-life experience?
@louis while i do not have advice for tile-integrated solar system, zach jerryrigeverything had a recent sponsored video installing a full solar setup in his parents home. The overall process described in the video looked very achievable and price competitive, which i find refreshing compared to other solar setups https://www.youtube.com/watch?v=JcKq6neGxXk
@louis also,, get quotes and system buildouts from at least two solar installers. I’m really interested to hear how the details work out in Germany! Green Mountain Power here in Vermont is very pro solar and our state has fantastic tarriff structures. Prior to heat pumps, we basically laid nothing for electricity to the grid. After heat pumps, we’re paying some, but less than our oil costs. That’s with us running a 400 gallon hot tub and keeping thermostats at “in-law visit” levels 😅
@louis i would keep the two systems separate. You don’t want to have a limited range of roofers able to fix roof problems, nor tie the failure mode of one roof to failure mode of panels and inverters etc…
Doing the panel system after the roof is best, and having some solar installers provide feedback on roofing plan may help ensure any tricky spots or materials align between the two.
We redid our roof, conventional tar shingles prior to putting up our solar install. i preferred separate systems for the reasons i stated, also able to optimize solar components and use US made panels. Lastly, we had tree coverage that we expected to change, when it did three years later, we easily extended the separate solar system.
@craigbro That are very good points, thanks for your valuable input! Do you also have a battery and what is your ratio between generated kW and battery capacity?
