Gaitheri Secondary School Solar PV Roof



Country:
Kenya
Why to choose this solution?
The iron-sheet roofs is covered in tiles fitted with energy-producing solar cells - an innovative solar-power technology known as building-integrated photovoltaic (BIPV) to offer an alternative to adding solar panels on top to produce power from the sun energy. This has enabled students to improve their performance thanks to more reliable power, which means they can study even after dark. Also provides solution to costly and unreliable national grid power.
Savings per day or production:
The solar tiles have reduced the school spending on electricity from KES 5,000($50) which is largely a fixed charge for access to grid power to 1,500 Kenyan shillings (about $15) a month, ie KES 50 (USD 0.5) a day. This has translated to savings of about KES 3,500 (USD 35) per month.
Cost in money and in own time to construct:
Grant of USD 2,000 (KSH 200,000) from the United States African Development Foundation (USADF) through Young African Leaders Initiative (YALI) was provided to implement the Gaitheri solar roof project.
Lifetime:
30 years, unless it is dropped.
Maintenance needed:
The only maintenance required by the system is to clean the tiles regularly, when there are covered with dust or leaves.
Resources needed in use:
Iron sheet roofs, Building Integrated Photovoltaic (BIPV) tiles, sunlight, power control unit, a battery bank of 8 Volts batteries.
Problems and limits:
Installing solar panels on the roof is expensive. It is affected by cool, cloudy or foggy weather. Market penetration is still slow given the technology is new and will require some time to build trust and acceptance among a wider customer base. Lack of awareness on the potential of photovoltaic.
Where and how can you get it or make it?
Is available in Kiharu Constituency, within the Muranga County. The system is provided by Strauss Energy.
Skills needed to produce, install. maintenance, use:
Production, installation and maintenance need fields of engineering, energy and construction. The use requires only a short introduction.
How to use it:
To be added
How to maintain it:
Not relevant
Climate effect (if any):
The school no longer use kerosene and candle that emit smoke which is a source of global black carbon that consequently result to global climate change.
Where it is used and how many users are there?
Used in Gaitheri Secondary School, which has 275 students, with student enrolment every year.
Why is it successful?
Successful because it ensures uninterrupted power supply for the ICT lab, The system has a power control system, there is no danger of power surge that used to destroy plugged-in electrical gadgets after a blackout thus reducing related losses for repair or replacement of affected gadgets.The system also has little operation and maintenance cost.
If you can make it, a short description, typical problems, materials needed.:
Materials include iron sheet roofs, Building Integrated Photovoltaic (BIPV) tiles, power control unit, a battery bank of 8 (Volts) batteries.
How to make it (if possible):
Not relevant
How is it delivered and by whom?
The business model is installation by Strauss Energy providing renewable and cost-effective energy through BIPV technology, a revolutionary solar-powered roofing tile designed and made in Kenya. Through the YALI program, Strauss Energy received a grant of USD 2,000 from the United States African Development Foundation (USADF) to implement the Gaitheri solar roof project.
