Looking to buy land in a hilly region (Ozarks). Is there an online solar calculator that can provide sunlight hours based on GPS coordinates? I am buying land out of state remotely so I can't actually visit the site. Some nice lots have an uphill grade on the south side which means solar will...

In a nutshell planning a new 5kw system with battery backup. No grid tie. This will be professionally installed on a new home build in the Ozarks where summer temps reach 100 degrees on warm days. Have gotten a quote for a system with an 8kW Sol-Ark inverter with EMP protection (5 year...

This may be an ignorant question but I am planning to build a new home with a 5KW solar only system including battery backup (not grid tied). I just read that if the house is wired for solar (DC only) an inverter is not required? Is that true? I read appliances like a fridge that use motors...

Found this Sol-Ark PowerPoint for educating people about battery life and different brands. Really interesting stuff! I couldn't find the link here when I searched so hopefully this hasn't been posted a bunch of times before. The slide on Tesla Powerwalls was eye opening all on its own! If they...

Trying to estimate wall space required for a Victron system. Will have two MultiPlus-II inverters and a Lifepo Battery. I have the dimensions on a battery but don't know how much overall wall/floor space all of the equipment would take up. Planning to put it in a 10' x 15' pantry.

I am trying to get an idea of how reliable properly installed off-grid solar systems from a reputable company are. How different is it from simply depending on the grid? Under normal usage how often do you need to interact with system to keep it running well? Once a month? Once a year? And is...

I am in the initial planning phase for a 1000 sq ft offgrid home (using a general contractor, no DIY stuff). Will have a 5-8KW solar system with battery backup however I think a portable propane generator may be wise (I don't want to lose a freezer full of food if the solar goes out, plus will...

Bought a wooded lot -- how do I estimate the amount of trees that need to be cleared for optimal sunlight? Lot is flat and located in Arkansas (the Ozarks) if that matters. The panels will be ground mounted. Is there a calculator of some sort? I don't want to remove more trees than is...

After having learned that many systems do not provide 240v, and adding it would be pricey I don't think it is required. No central a/c, electric stove, dryer, or big power tools. I thought the well pump may require it but it appears they even make deep well Grundfos pumps and electric lawn...

Victron 6kW with 15kW battery (no mount or install) ($13k) Sol-Ark 5.4kW with 15kW battery, rack mount, emp hardened, and install included ($32k) Enphase 8kW with 10kW battery, rack mount, and install included ($32k) This is an off-grid system that will be professionally installed in a new...
