For 'solar power', solar panels that produce electricity you need daylight (the sun needn't be direct). There isn't really a second condition although many factors improve how much electricity is produced by the panels:
Orientation:
Better performance will come from mounting the solar panels to face the sun, and at any angle to the ground. The best angle depends on where you are on the earth. Also, the array of panels should also face the same direction For example, half the system facing south east, and half the same system facing north will degrade the performance of the whole system.
Shading:
No shading at all accross the whole system will improve performance. To put it another way, if you were to shade a quarter of an array of Photovoltaic panels, then you will degrade the performance of the whole system. No shading at all is best.
System sizing:
If the system is to provide AC power to a house, then the number of panels need to be well matched to the inverter or inverters. The better the match the higher the effieciency of the whole system.

Why are solar panels so important?
Solar panels are important because they don't cause pollution, and they can increase the production of electricity in the world. Another Answer: Solar panels, as of today, produce virtually non of our annual power needs. I also are far from being a pollution free device. There is a variety of very nasty chemicals and gases used to make these panels. They rarely supply as much power as it takes to construct one. They do however, have some very useful applications where they work well. 1. Space. The power they produce can be very useful in keeping our satellites supplied with power. 2. Remote applications. Power far from the grid is needed and solar is a quiet method of getting small amounts of power 3. Back up applications. When the grid fails, solar panels can supply quiet limited power. It is hoped that solar panels will become more powerful and useful as the technology develops. Until then they still have a working location in our world.
What is a renewable energy resouce that is used to power the hubble space telescope?
HST runs on electricity supplied by massive Power Supply Units, which get their electricity from the 2 huge Solar Panels on either side of the spacecraft.
How much land would need to be covered in solar panels to replace one nuclear power plant?
A typical Nuclear Plant with 4 units active generated 13,000 Megawatts of Electricity. A single Solar Panel Generates Just 200 Watts while its sunny. 1 mega watt is 1 million watts. 13,000 Mega watts is 13,000,000,000 Watts. So we divide 13,000,000,000 Watts by 200. we need 65,000,000 Solar Panels. 1 Solar panel covers approximately 4 by 4 Meters. So the area is 16 metre^2. 65,000,000 Multiplied by 16. 1,040,000 Kilometres of land.
What is the normal or average mass of a red giant?
The mass of a red giant star varies between 0.3 and 8 solar masses. The solar mass is approximately 2 X (10) to the power 30 kilograms. In other words is pretty heavy.
How does the sun release heat?
The surface temperature of the sun is approx. 5,500 °C Heating power: The solar constant on earth is 4000/3 watts/m^2. Given the sun is 150Gm away the heat given off at the sun is the solar constant times the area covered, 4pi r-squared, (4e3/3)x4pi (150e9)^2= 377 e24 watts. This is a lot of heating power.

What are good things about solar power?
1. Solar Power is not tied to specific locations. Power can be anywhere 2. Solar Power is silent 3. Solar Power is more steady and readily available than Wind 4. Solar Power is easy to store 5. Solar panels are attractive. They can be made into art 6. Solar Power can be a very automated backup power 7. Many Governments help with the return on investment to make them a workable alternative. 8. They do not consume power from the grid like wind to get started or protect themselves. 9. They are considered by many to be green energy
What are some positive effects about solar power?
1.Most solar energy doesn't take any power to run and produces no pollutants.2.Solar energy (sunlight) is free and virtually unlimited.

What energy transformation's in a solar powered calculator?
The energy transformation that is in a solar powered calculator is:Device: Solar-powered calculatorInput:Solar energy and Chemical energyOutput: LightThere is 2 ways a Solar-powered calculator is worked by: Solar power and batteries. In the batteries there is chemical. On the solar powered calculator there is a little solar panel. The calculator needs light to power it up. If there is no light the batteries would be it's backup. The numbers are shown by light that the power or batteries and solar power would produce.
What is the advantage of using solar cells?
1) it produces electricity without pollution 2)the power you get from it is free 3)once set up you don't need to do anything
Is solar energy currently being used?
Yes, in many places. See Wikipedia 1. List of solar thermal power stations 2. Photovoltaic power stations
