South-facing solar panel systems almost always generate the most electricity, but east-west roofs can work well for solar, too. The direction is more important than the angle. Angle is rarely a make-or-break factor, and most roof tilts will work fine—though there are some exceptions. [pdf]

No matter if you’re installing a small 2 kW system or a huge 20 kW system, take some time before your installation date to perform some easy energy-efficiency measures. Replace incandescent light bulbs with LEDs, add weather-stripping around doors and windows, and install low-flow. .
While installation costs vary by region and installer, in 2016 the National Renewable Energy Labfound residential solar installations in the US cost an average of $2.93 per watt before. .
$24,612 is quite a lot of money, so the next logical step is wondering how much can you save with a 12 kW system. If you save more than you spend, it makes financial sense to install! So. Compare price and performance of the Top Brands to find the best 12 kW solar system with up to 30 year warranty. Buy the lowest cost 12 kW solar kit priced from $1.10 to $2.00 per watt with the latest, most powerful solar panels, module optimizers, or micro-inverters. [pdf]
