Solar Power Energy

How can I measure Solar power/energy?
What kind of instrument/tool can I use to measure the amount of energy produced from a solar-powered oven/appliance? And what would the unit of measurement be? Volts? Watts?
(It’s for my science fair project)
Your solar appliance is not producing energy. You can calculate the amount of energy you need to add to a liter of water to raise it one degree C. But a solar oven is not linear. That one degree of temperature rise is much easier to accomplish at 25C than at 80C. To do a project on energy, you need to learn at least the basics of energy.
