Rwanda Looks Forward to Second Phase of SolaRwanda

Submitted by Baerbel Epp on December 12, 2018

The Eastern African country of Rwanda has plans to extend its national SolaRwanda programme. Backed by the World Bank, the Global Environment Facility and the Nordic Development Fund, this support scheme has subsidised 3,400 residential solar water heaters since it was set up in 2011. Energy Development Corporation Limited (EDCL), a government agency established to promote investment in new energy generation projects, is now seeking a consultant to plan the second phase of SolaRwanda.

EDCL advertised the consultancy position in July. Work is to be carried out over a period of 60 days. Vetting has not yet been completed.

The consultant is to create a report in which he or she will evaluate SolaRwanda’s first phase, which started on 1 April 2011 and will end on 30 December 2018. The document is to include detailed descriptions of potential challenges regarding program design, lessons learned and recommendations to improve the support scheme. The programme has reached only a third of the initial installation target, set to 12,000 solar water heaters in the first phase.

The report is also expected to provide insights into the development of capacities for assembling and producing solar water heaters and the growth of a local import structure. EDCL said that the consultant would be hired to design the second phase of SolaRwanda and give recommendations on how to mobilise funding to support the scheme in the future.

SolaRwanda offers subsidies and loans

During SolaRwanda's first phase, originally scheduled for implementation between 2011 and 2015, EDCL has offered grants and loans to buy solar water heaters that were certified via the programme and conform to the global Solar Keymark standard. The flyer attached to this article lists other requirements that need to be met when applying for the subsidy.

Grants have ranged from USD 150 to USD 400, with the precise amount being calculated based on SWH storage tank capacity and pressurisation. EDCL confirmed that the 3,400 installations subsidised in the first phase had all been pressurised systems.

The SolaRwanda scheme has paid owners of systems with a minimum pressure of 2 bars between USD 250 for a 200-litre and USD 400 for a 300-litre solar water heater. All households also received a loan of USD 800 (for a 200-litre system) or USD 600 (for a 400-litre one), to be paid back in two years. That the loan will be repaid in 24 instalments is part of the contractual agreement between the user of the system and EDCL.

High Quality Compact Pressurized Heat Pipe Vacuum Tube Solar Hot Water Heater

The Characteristic:

1.The water will not flow into the tubes directly , the system will still work even the tube broken.

2.With Intelligent controller.

3.Anti-freezing, all-year-round service even in extremely cold area.

4.Adoping the best conduction performance metal copper(heat pipe).

5.Directly connected with city warer without a circulation.

6.Working pressure(0.6MPa).

Working principle:

Integrative pressurized series is a renovation model for the solar hot water, which adopts advanced heat pipe technology, combines heat pipe solar collector with pressurized tank to form a compact model.

The vaccum tubes absorb and convert solar energy into thermal energy, and transfer to the central heat pipe via the aluminum fin. The heat pipes have tiny amount of purified water sealed inside at depressurized condition. when heated, the medium inside the heat pipes vaporizes at low temperature(about 30℃), the vapor rises to the condeser and heat energyis conducted to water(inside the tank),When vapor is cooled down, and becomes condesate, falling to thebottom of heat pipe. By the continuously circulating in this way, heat is carried from outside to the water inside the tank.

Professional Manufactory Made Heat Pipe Vacuum Tube Solar Collector

Heat pipe solar collector working principle:

1. The heat pipe series solar collector are always connected with existing heating supply device.

2. The selective coating on the inner Cover of the evacuated tubes converts solar energy into heat energy and transfers heat to the heat pipes by aluminium fins.

3. The liquid in the heat pipe changes into vapour which rises to the condenser.

4. The heat then passes through the heat exchanger and the vapour becomes liquid, returning to the base of the heat pipe.

5. The heat conducts to the heat transfer liquid (anti-freezing liquid or water) via a copper pipe.

6. This transference of heat into the liquid creates a continuous circulation as long as the collector is heated by the sun.

Heat pipe solar collectors specification:1. Manifold (interior): 0.8mm thickness Red copper
2. Manifold (exterior): 2.0mm thickness Aluminum alloy
3. Glass tube dimensions: 58mm x 1.800mm
4. Insulation layer: polyurethane foaming
5. Heat preservation: 72-96hrs
6. Hail resistance: 25mm
7. Max pressure: 6 bar
8. Coating of vacuum tube: Ss-c/cu
9. Frame: 2.0mm thickness Aluminum Alloy

Heat pipe solar collectors applications:1. Hotels, resorts, hospitals and hostels
2. Process industry, boiler feed, laundry and canteens
3. Agricultural sector, hatcheries and dairies
4. Process industry, Boiler feed, Laundry and canteens
5. Agricultural sector, hatcheries, and dairies
6. Swimming pool heating
7. In-process heating
8. Health clubs (Steam / Sauna)

Working Principle:
The SS-M series, in streamline closed circuit systems which are recommended for frost prone and poor water quality situations. Antifreeze fluid is used to circulation through the collectors. The heat collected from the panels is transferred from the fluid pipes to the water tank by a heat exchanger. The circulator is regulated by a control unit on the water heater. This ensures the optimum use of the sun’s free energy. Copper coils exchanger can realize the cycle for solar energy and the cycle for electric heater or gas for supplementary energy to ensure you always have hot water on tap at any weather.
