Solar energy
1. Are we really convinced with the abundant number of required solar panels – for a given energy output – associated with the relatively lower energy density of solar power – in addition to the inconsistent amount of power production that vary by the season as well as by weather?
2. Whether the solar panels would always acquire the required (range of) frequencies of sun light to be hit on the panels – so that the conversion from solar to electrical energy could take place efficiently?
How about the factors that obstructs the sunlight from reaching the panels?
Feasible to have sophisticated solar panels - that would always track the sun - so that the panels could always be kept at right angles to sun rays - in order to harness the maximum energy output?
3. On an average, solar energy costs around 5 cents per kilowatt-hour, while fossil fuels costs around 5 – 15 cents per kilowatt-hour. Will this aspect of solar power would really make an advantage over fossil fuels in the long run (despite its elevated startup costs) – with reference to 15-20% efficiency of solar energy as against 40% efficiency from coal and around 60% efficiency from natural gas?
4. How easy would it remain to deduce the best size (geometry) of solar panel for a given task that would end up with the optimum performance while requiring a low-maintenance with maximum energy?
5. Having known that a solar panel hardly converts one fifth of the total amount of solar energy impacting on it (and thereby requiring more number of solar panels), while the solar panel only produces direct-current and hence, we require an inverter to convert the same into an alternating-current power; don’t we see the associated complexities in the long run?
Feasible to prevent fire outbreak in inverter and solar installation always? How will you deduce the correct size of cable gauge for installation? Easy to ensure that all cable terminals (battery, inverter & solar charge controller) remain properly tightened that avoids partial contacts, if any, to avoid the generation of sparks, and in turn, fire outbreak?
Feasible to ensure that battery by the inverter and/or solar charge controller remain not overcharged (causing rise in temperature and thereby leading to fire breakout)?
How do we avoid over loading? Whether all the inverters have the required overload protection?
6. On a lighter note, do I need maintain so carefully a 10 - 15 KW inverter system, a 10 -15 KWp solar array; 30 – 40 KWH Lithium Battery bank (the solar panel system) in order to power few lightings, TVs, Fridge and few inverters @ my residence?
