How much does solar cost?

As of July 1, 2018, here in the Bahamas, the average cost of a professionally installed, code compliant off grid battery based solar system (using maintenance free lithium batteries) is about $6.97 to $7.10 per watt. The average cost of the same size grid tie battery-less version in is about $5.95 to $6.05 per watt installed. The average home consumes about 600 Kwh of electricity monthly, which would require a 5000 watt off grid battery based solar system, which equates to about $35,500.00 (5000 x 7.10) BSD. The same size system grid tied without batteries would equate to $30,250.00 (5000 x 6.05) BSD.

A simple formula to get an idea of how much solar you need; take the average monthly Kwh consumption, multiply by 1000, divide by 30 (days), divide by 5 (sun hours) then divide by 0.65 (systems efficiency). You would then multiply this number by the cost per Kwh for the type solar system you want to install to get an idea of the cost. An Island Solar professional would still have to conduct a site visit to produce a more accurate estimate for your building.

I would love to invest in solar, but I think my roof is too old. Am Iout of Luck?

There is always the option to have your solar panels on a ground mounted system, build a pergola or even a solar car port.

What happens to solar panels when it rains or is cloudy?

During rainy/ overcast days your solar panels still produce energy although not as much as clear sunshine days

What rebates are available for solar energy?

You can get your solar kit imported duty free in the Bahamas by first writing a request letter to the Ministry of finance with attached invoice

Would it make sense to go solar if we use most our energy at night?

Yes indeed, energy from your solar system can be stored in batteries during the day to be used at night when there is no sun.
