so, what you have now is typically a bill from p.g.nd e., a gas portion and an electric portion cleared marked. look at the electric portion. you'll get a usage area and a box at the end. it will break down like this. it says five rate tiers you call them. you get a baseline rate at a cheap amount. you get another 30% amount at a cheap rate. this is your baseline rates, these two. but when you use more, you pay more. and what it looks like graphically is, boy, there is a lot up here. so these rates are where your big expenses come. if you're in these rates, solar can make a lot of sense. they go up very dramatically, 222 cents, 32. let's say we have a case study. you have a $100 electric only. that's $1,200 a year. after 10 years, it's $12,000 if rates don't rise. let's assume that rates rise at the historical average which has been 6% over the past 30 years. so let's assume -- i think that might be conservative, let's assume that. so that means that after 10 years, you'll probably have paid out $16,000 and your bill by then will be $1
