Solar and Wind

Wind is inconsistent

Wind energy has a lot in common with solar energy in terms of consistency. Solar produces 5-6 hours per day and wind produces 8 to 9 hours per day. Although wind energy qualifies as a renewable resource, wind speeds fluctuate each day. This can be a big disappointment to wind turbine developers who will commit every penny and every ounce of energy in the project only to end up with fluctuating wind patterns.

Solar is not 100% Reliable

This means that when the sun is not shining, there is no generation of energy. The generation of power is mostly affected at night and during winter months. Most people have now invested in battery backup systems, which store up power to be used when the sun is not shining. However, investing in backup systems can ramp up the overall cost of installing a solar panel. It mostly ends up not adding value to the solar energy technology.

High Capital Costs

Although installation of solar panels would bring immense benefits in the long run, the upfront costs can be punitive. Depending on the company you choose to buy solar panels from, it could cost an arm and leg. It’s even difficult to quantify the entire cost of installation without the help of manufacturing companies. Some nations have introduced rebates and tax credits to enable lots of people to install solar panels, but unless you are putting some money aside for this, it can be an unbearable cost. Also, it might take up to 10 years to 15 years before you can break even with your initial investment.

Negative Energy Balance

The fact that the sun is unpredictable means solar energy cannot be relied upon to power a country’s economy. Solar energy technologies are still being developed, and scientists predict that the technologies will be able to cater to a majority of world population by 2020. Until then, we will still rely on fossil fuels as the main energy source.
