Solarspace - Cost Savings with Solar

By: Solar Space  11-11-2011
Keywords: solar water heating, Water Heating

Does it really make sense to switch to solar? Water heating counts for 40% to 60% of the monthly electricity bill. Accumulated cost savings with solar water heating are between 32,000 Rand and 47,000 Rand after only 5 years provided that electricity price increase is only 25%/year. Bearing in mind that the lifespan of our solar systems is 25+ years you will enjoy free hot water from the sun for more than 20 years.

Estimated electricity cost saving by using solar water heating (assuming 40% of electricity bill counts for water heating - electricity price increase 25% each year)

Current electricity bill R 800/month = R 9,600/year
