It seems weird to "like" your comment, but first hand experience like this is invaluable for people investigating and researching solar.Half of our system is made of factory laminated glass panels. At the time they were the only made in WA panels available and required for the maximum credit. The lamination started failing in the field at about 5-6 yrs. It seems inevitable with the heating and cooling of the panels. A couple of our panels are starting to show delamination in the corners. We thought we were well covered with a 20 yr warranty but the company moved out of the state to avoid claims and then went bankrupt. No more laminated panels here, the second half of our system is made of conventionally manufactured panels.
That's unfortunate. I'm surprised to see so many delamination failures. There are laminated glass products in use that get tons of light and heat but don't delaminate. What makes it such an issue with solar panels vs a windshield?That's why we're here. Not every experience or stove is golden. If our experience can help someone else then there is some value there. Our panels have the cells laminated between 2 thick sheets of tempered glass. There may be other more durable lamination processes out there, but personally I would stick with some of the better proven brands and technologies unless the price is exceptionally good. What burned us is that the sales pitch was that these were a superior product. They certainly carried a high price.
Do yourself a favor, buy this book" Solar Power your home for Dummies and read it. It covers all the basics. Note given your location, panel angle and snow management is a significant issue. If someone tells you it isnt an issue find someone else to talk to. Unless you have a lot of cash to burn up front and long term, do not go off grid and realize that off grid requires a different far more complex design that very few contractors are skilled with since the vast majority of solar systems are relatively plug and play grid tie systems.It's all good info. I am still trying to figure this stuff out. I end up with more questions than answers every time I do a little reading. The poco is having a seminar a week from today. Luckily it is on a day off and starts after dark. I have plenty of questions regarding the house and the solar well pump. I am more confused than when I started thinking about this.
The good news is the septic is finished. Standing in the driveway looking sidehill, I have the cistern gravity feeding into the house, and further down the hill the septic gravity fed from the house. Even a couple of years ago, I would never have thought I would be trying to limit my use of the grid.
That's the way we fly, though it is painful during an outage on a sunny day when the solar panels sit offline.I agree planning for efficiency and an inevitable long outage is the way to go. Just hard to beat the cost of a generator and transfer switch for when it happens compared to the high initial and ongoing cost of off grid.
Yep from what I heard on a podcast ( https://theamphour.com/443-an-interview-with-jp-norair/ btw) the high temperature features are validated already, but I don't know what that means. I do know that with GaN FETs for the inverter and such, they can probably use smaller capacitors (& inductors) which might enable the use of ceramic capacitors, which tolerate super high temperatures.Yes, batteries generally don't like to get too hot. Heat and lack of sufficient battery cooling killed the Nissan Leaf in the southwest. Hopefully they are using heat tolerant capacitors in the inverter or they will fail prematurely as well.
It's probably MORE painful down here on the edge of the tropics after a hurricane when my generator and every neighbor's generator in our suburban neighborhood is screaming away at 3,600RPM, while our 4.4kW PV array on the roof sits quietly idle. That's the way we fly too...That's the way we fly, though it is painful during an outage on a sunny day when the solar panels sit offline.
I have an all electric house, and the end of the nearest NG line is 4 houses down the street. Getting NG to me wouldn't be free, and when I looked up the minimum monthly cost to have a gas connection, I was astounded to see they get $35/mo just to be a customer before the first therm of energy comes through the pipe... At that rate, I could just stock up on gasoline for hurricane season, and give it away in December...I go for even less complicated by running our generator on propane. No drain, just turn it off. Oil is much cleaner too.
