Solar Energy for Houses: Reality or Pipe Dream?

The intense media apparatus unleashed by solar panel producers should not make us avoid the necessary analysis of the real possibilities currently offered by this technology for homes.

Monday, October 20, 2014

In addition to the cost of purchasing and installing a solar panel, the climatic conditions of our tropical countries must be taken into account and the amount of energy this form of alternative energy produces during wet periods.

Sergio Morales, assistant coordinator of the Electronic Systems Laboratory for Sustainability at the Technological Institute of Costa Rica (TEC) told that "... one solar panel, the largest size that can be achieved in the country, can provide 400 watts of energy instantaneously, but only if we are in the middle of summer. For example, a stove disk can consume 2,000 watts in an instant. If you have in your house 10 70 W bulbs, these bulbs consume more than the panel will produce."

He added that "... In the TEC there are ongoing investigations to determine how resistant solar panels are in wet conditions such as those that exist in the country.
