The Break-Even on a Solar Water Heater Investment
has been reached

Rising electricity prices combined with low interest rates and generous Eskom Rebates makes solar water heating systems a good investment. Based on current figures, your repayment is less than your electricity savings.

We have done several installations for the hospitality industry. Read the case studies below to see how solar heating can help guest houses, hotels and other accommodation venues benefit in terms of cost and sustainable solar power.

Case Study One:
Guest House
Oranjezicht
Cape Town

Situation:
6 rooms, one 450 litre and two 250 litre electric geysers, consumption ca. 1200 units per week

oneSolar

Solution:
Three flat plate collectors were used to heat the 450 litre geyser - this one pre-feeds the two 250 litre geysers in parallel installation with hot water - this ensures 100% availability of hot water.
Outlook:
An additional one panel for each of the 250 litre geysers was added, to compensate for the heat loss on those geysers.
Cost:
R 35,000 incl. VAT
Savings:
R 9,500 in year one, R 11,800 in year two, R 14,900 in year thee = R 36,200 over three years.
After that, the savings on the electricity is adding straight to profit - this accumulates over the lifetime of the panel of 20 years to 200.000 units (R 300,000).

Case Study Two:
Boutique Hotel
Sea Point
Cape Town

Situation:
Ten rooms, five 150 litre geyser and one 250 litre geyser.
Solution:
A consolidation of geysers was done to configure four larger solar systems which have been fitted with evacuated tube collectors.
Outlook:
When the geysers burst, the current geysers were replaced with larger tanks offering ten year warranties and 20 year life expectancy.

Cost:
R 65,000 incl. VAT

Savings:
R 12,200 in year one, R 15,200 in year two, R 19,000 in year three, R 19,000 in year four = R 65,400 over four years.

After that, the savings on the electricity is adding straight to profit - this accumulates over the lifetime of the panel (20 years) to 230.000 units. (R 350,000)

Case Study Three:
Boutique Hotel & Villas
Bantry Bay
Cape Town

Situation:
Three pools (30sqm, 20sqm and 65sqm in size) with the 30sqm pool being heated by a heat pump, 200 meters of pipe run necessary to go solar.
Solution:
Three solar pool heating systems (six panels, four panels and 14 panels respectively in each pool), plus customer requested automatic temperature controllers.
Outlook:
Solar water heating was implemented for the domestic consumption of the hotel.
Cost:
R 90,000 incl. VAT
Savings:
For this luxurious high-end hotel, the ultimate comfort for the customer and a green conscious appearance has been the main driving factor. The lower operating cost of solar water heating and the higher savings over the total life expectancy of the solar pool heating panels have driven the decision to go solar rather than using heat-pumps.

Case Study 4:
Bed & Breakfast
Hout Bay
Cape Town

Situation:
Five geysers in total of which one 200 litre geyser burst.
Solution:
Replacement of the burst geyser with a 200 litre solar geyser with ten year warranty and one flat plate collector panel with ten year warranty.
Outlook:
Every burst geyser in future will follow the same strategy.
Cost:
R 23,000 incl. VAT - Insurance Pay Out: R 6,500 - Eskom Rebate 5,500 = R11,000
Savings:
R 3,150 in year one, R 3,975 in year two, R4,970 in year three = R 12,095 over three years.

After that, the savings on the electricity is adding straight to profit - this accumulates over the lifetime of the panel (20 years) to 60.000 units (R95, 000).

Besides the obvious financial sense this investment is making it is even more viable for the hospitality sector. The reason is simple: bed & breakfasts, guesthouses, lodges and hotels have their major expense on hot water during the summer months when their occupation rate is high. This is the time when a solar system brings the maximum output due to the high sunshine hours.
