According to a
new study by the Pecan Street Research Institute, solar panels
should point west instead of south, as previously believed.
Experts at the Pecan Street Research Institute have found that the key to
solar panel efficacy is not only how much electricity is produced but also when
it is produced. West-facing solar panels produce 49% more
electricity during peak demand time than their south-facing counterparts.
In Texas, as in most places in the US, peak demand times are 3 p.m. to 7
p.m., which also corresponds with the heat of the day. Peak demand time happens
when people arrive home from work and begin turning on lights, using
appliances, etc. This is the time of day power grids are most likely to become
overloaded and when electricity is most expensive.
If clean electricity is produced from
correctly-facing solar panels that are more effective, this will reduce the
stress on the grid. Experts
stress that incentives for solar panels should be aligned so that energy
production follows peak demand – something that is not happening right now.
