Should I go with the larger system?

Should I go with the larger system?

Hi Everyone,

I have been doing a ton of research over the last month and have already spoken to several local installers here in Maryland about getting a roof-mounted system on my house. Our total usage is around 27,000 kWh per year. We received several quotes and have decided on a highly regarded small company, however, we're torn on whether we should go with the larger system that would offset 97-100%+ of our usage, or the smaller system that would offset 71-75% of our current usage.

With the degradation of the system over time, it seems like the larger system makes sense, however, we 1) would have to shell out quite a bit more money, and 2) would have to put panels on the garage and feel like that would make it more difficult to sell our house down the road should we need to move, however, we do not plan on moving for at least 10+ years.

Pay back period for either system is 8-9 years based on total production using conservative numbers and estimating an escalation of price from $0.14 kWh of 3.5% per year. I did not factor SRECs at all since they're going for only around $6 right now in MD. If that market changes, obviously the pay back will decrease too. Our utility does offer net metering at a rate of $0.06.

​

Any thoughts or insight regarding the system design? Thoughts on going for the smaller system vs. the larger one? I will be using cash and feel like this is a good investment as it hedges against increasing prices over time, not to mention my family's extremely high-usage.

Solar Supports

Solar Supports I'm looking at installing a solar system at our off grid cabin this spring and I'm trying to come up with a good way to get the panels up high enough to catch decent sunlight. The roof of the cabin is not an option as there are some trees blocking it but I do have a shed that I figure I'd be able to brace the supports to, I can't use the shed roof either as it's facing the wrong direction. A couple neighbors have systems which they've put on poles that go up sort of like a street lamp or flagpole style support which is an option but I thought maybe either a frame like a scaffold kind of thing secured to the back of the shed might be a more sturdy option. What have you guys used to elevate your panels on a standalone frame, or have you seen any companies that sell good kits? I'm in BC in Canada as well. Thanks for reading. submitted by /u/dykehoncho [visit reddit] [comments] https://ift.tt/2C1elG6
