To be sure your system is supported throughout winter and rainy days/weeks we recommend you oversize your solar panels. We can install a battery cabinet that can be added to in the future or you can calculate your load and cover it with battery power. For your inverter we also recommend you oversize, calculate how much energy all of your appliances use and choose an inverter that won’t overload. A generator should be sized accordingly to the battery charger output. Consider the amount of batteries you need to charge now, and in the future should you choose to upgrade. For example, if the charger charges at 50Ah for a 48V battery bank (50 x 48 = 2400) a 2.4kW continuous output generator would be sufficient.

t all depends on what you want to run.If you only have a few lights to run you could install a very small system, costing only a few hundred dollars.The average three bedroom house uses between 10-30kW per day. Power used during the day can be run straight from solar panels, whereas power used at night has to be run from the grid, batteries, or a generator. Once you calculate what you are using and when you are using it, you can size a system accordingly to suit your needs. A general off-grid system to cover these loads could cost anywhere from $10,000 - $20,000 up to a maximum of around $60,000 - $70,000, depending on the components.

1kW of solar power can supply for approximately 4hrs per day. 1kW is worth approximately $0.25 if you use it yourself, and only $0.125 if you sell it.
If you use it yourself, you can save up to $1.00 (or sell $0.50) per day per kW of solar panels installed. We recommend sizing your system to cover all of your daytime usage and ideally to produce enough power in the day to cover some of your nighttime usage, fill up batteries, or sell.

Lithium. The life expectancy, warranty, and ease of use of lithium batteries is superior when compared to lead acid batteries.

High quality panels have a higher efficiency over their complete lifespan and a longer warranty. It’s better value (for you and the planet) to invest in solar panels that will have the longest lifespan.Top brands with the best warranties (up to 25 years) are SunPower, LG, and REC.

North-facing solar panels are most efficient if you use majority of your power during the day. If you use majority of your power in the morning and evening you want your panels facing east and west. Panels should not lay flat as they can pool water, they should be angled between 15-30°.
