Solar Panel Tilt Angle in Puerto Rico
So far based on Solar PV Analysis of 39 locations in Puerto Rico, we've discovered that the ideal angle to tilt solar PV panels in Puerto Rico varies between 17° from the horizontal plane facing South in Isabela and 16° from the horizontal plane facing South in Arroyo.
These tilt angles are optimised for maximum annual PV output at each location for fixed-panel solar PV installations. If you click on one of the locations above, there is further detail on ideal seasonal tilt angles as well (in case your solar panels are adjustable).
Depending on where you are based in Puerto Rico, the ideal angle to tilt your solar panels will vary by approx 1 degree (between 17° from the horizontal plane facing South and 16° from the horizontal plane facing South).
Puerto Rico solar PV Stats as a country
Puerto Rico ranks 48th in the world for cumulative solar PV capacity, with 491 total MW's of solar PV installed. Each year Puerto Rico is generating 154 Watts from solar PV per capita (Puerto Rico ranks 33rd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Puerto Rico?
Yes, there are several incentives for businesses wanting to install solar energy in Puerto Rico. The Puerto Rico Energy Commission (PREC) offers a net metering program that allows businesses to receive credits on their electricity bills for the excess energy they generate from their solar systems. Additionally, businesses may be eligible for federal tax credits and accelerated depreciation benefits. The PREC also provides grants and loans to help offset the cost of installing solar systems.
