I would like to know an estimate on how much time it will take to make the apps; for me this is important due to the cost. Also I would like to know how much time it would take to make a website (details given below). I have no graphics and would like you to design them as well. There will be mathematical skills needed to calculate angles of sun (where the sun is every hour from sunset to sunrise, average in each month for any position on earth) and the sun’s effect on the efficiency of solar panels. Formulas can be found on internet.
I would like an App for android and iOS that helps people plan a solar panel array. It collects information about the location of the user (by GPS and letting the user finetune the position via a google map). It collects the orientation of the panels (holding phone same direction as panel or entering manually), type of panels (enter manually size, orientation and energy output of a panel) and number of panels (enter manually or calculate maximum possible on roof by entering roof type, size and unusable part of roof). By pointing camera at obstacles along the horizon (only needed where the sun travels on the longest day) it can calculate the amount of shade on the panels) and efficiency of the position. It estimates the energy the panels generate per year. When all information is entered the analyses of the situation can be looked at by the user. Here they can see estimated energy per year, efficiency of the location and orientation, effect of shade on overall energy gain split up in separate months (in a graph). It allows the app to make and save photos of the roof. Information is stored in a database that will be able to sync with a website.
The app will automatically adjust the information used and the language used based on the position of the user. Also must be able to choose between different units of measurement (metric etc.) and languages. First time users get a tutorial that guides them through collecting the information. After the first time this does not happen anymore except when this is turned on again in the settings.
I plan to have a website built that allows people to look at their data. The should allow people to ask for quotes from solar panel company’s. The website must allow for solar panel company’s to enter which location(s) they sell to and how much money they will pay to make an offer to the user of the solar planning app. When a user asks for quotes the 3 highest paying solar panel company’s will automatically receive the users information so they can send them a quote. This must all be programmed. I must also be able to view the information on how many quotes have been sent so I can send them a bill. The website must of course also give information about the app. Login via facebook should be possible and if the user creates a login on the app (via facebook should be possible) it should also be possible to login on the website with the same login. When people ask for a quote they cannot ask for it again for 1 week.
Initially the app will only work for the Netherlands but will soon work in more country’s. You can make it in English and I will make the translation for the dutch language. People will be able to choose the language. This is only a short description of the app but I would like to know if it is possible to be made and how much it will cost. I would like to know how much the website would cost as well. I will provide information about The Netherlands about the sun hours and solar panel efficiency with different angles and orientations (for the Netherlands). Other country’s will follow in the future and you can expect more work for implementing them (although this should not be too difficult and a system for this should be made while designing the app).
