PLEASE NOTE. This is a very early launch of a platform designed to update stakeholders and observers of Its Time solar schools’ projects. Current, historical and up-coming projects will be gradually added. As will the various information panels below. It is a considerable development project and we appreciate your patience as it evolves over the coming weeks. Almost certainly there will be a bug or two along the way - should you notice any issues or have ideas to improve the platform, your message is appreciated message via: iitime.org/contact-us

About

Dawara is remote in the west of Fiji's second largest island, Vanua Levu. 4 teachers are providing classes for 50 students from Year 1 to 8.

At the time of installation, the school had a disproportionately large and expensive to run generator that runs for small periods on a needs basis during the daytime and 2 hours each night supplying teachers’ homes (teachers supplemented with kerosene lamps and small solar lights). The teachers are excited about what new equipment this opportunity will bring to the school.

Notes

(1) This is the annual fuel consumption based on reporting from the school at the time of school survey and affirmed at the time of installation. It refers to direct fuel use by the school, not including teachers' homes.

(2) The fuel consumption of teachers' homes varies considerable between homes and over time. Their sources of energy varies from their own small generators to shared generators, still some use kerosene for lighting and some small solar (often failing) for lights and charging. Recently on Beqa Island two of the 7 households at one school were each using 10 litres of fuel per week and some were using very little. So, we have chosen the conservative underestimate of each household saving of 2 litres per week (approx. 5 kgs of CO2).

(3) Most schools have a cost to get fuel to the school - usually small boats and car/truck on the mainland. The costs vary from small amounts to some schools where the cartage cost is almost the same as the cost of the fuel itself. The cartage consideration (dollar and carbon cost) is a percentage of the total fuel consumption, because it varies widely from school to school we have chosen quite a conservative estimate.

(4) Includes cartage and teachers' home consumption estimate that therefore contribute to the total CO2 saving. But we do not include the teachers home in the financial saving - rather we just refer to the savings from the school generator.

(5) This is the current published diesel price in Fiji presented in AUD. Often the islands pay a higher price, but that is not factored in, so generally the price will be a small under estimation.

(6) Generators often require repairs and eventually replacement. That cost varies significantly from school to school, so a conservative value is applied to represent this component of cost/saving for all schools. It is not possible to calculate that accurately for every school, hence the estimate across all.

(7) Burning diesel produces CO2 at a rate of 2.68 kgs/litre, whereas petrol produces it at a rate of 2.31 kgs/litre. We have chosen 2.55 as the approximate for our calculations because there is more diesel used than petrol in the school generators.

(8) The fuel savings in the teachers' homes are not included in the calculation of financial savings for the school. Although teachers are asked to make a small contribution each term (FJD70) for their now 24-hour power and this goes to the school to buy more education resources.
