Cornerstone No. 189, page 5 rate. Our church will pay for the consumption shown on this meter and we will charge the doctors for their electricity consumption as indicated by their own electricity meter. The addition of an accumulator to store our excess electricity was not considered, as it was very expensive. As an additional subsidy is now available the situation is being reconsidered. We should receive a one-off subsidy of about CHF 8,000.- from Swissgrid and hopefully also a certain amount from the city council. The panels should be cleaned once a year and the tinsmith is expected to do that as well as carry out the other ordinary maintenance tasks (like cleaning gutters and rainwater pipes).
