What doesn't move, however, is a suspended mass inside the seismograph, called the seismometer. During an earthquake, the seismometer remains still while the case around it moves with the ground shaking.

Solar electricity costs about $10 to $12 a watt installed, though you may be eligible for state incentives. Check your utility bill to see your monthly usage. A robust solar electric system will cost about $20,000. You can spend as much money, to receive as much solar electricity, as you feel comfortable with.

Again referencing the latest US Solar Market Insight report, the average installed cost of a residential solar panel system was $4.72/watt.However, prices vary tremendously by region. âCommon residential system prices ranged from less than $3.00/W to just above $7.00/W,â the Solar Energy Industries Association writes.he bulk of the price of going solar is now the âsoft costsâ (installation, permitting, etc.) rather than the solar panel cost.
