This chart illustrates how electricity becomes more expensive the more you use. After the less expensive rate tiers are exceeded(in green), the electricity can double in price. If you ever wonder why your bill is large, this is where it happens. Turning a light on in the later part of the month can be twice and even three times as expensive as in the begining of the month. Breaching the fourth rate tier more than triples the base rate.
Solar reduces the amount of electricity purchased from the utility and can effectively keep you in the less expensive rate tiers. This also illustrates that it is not necessary to buy a system large enough to supply your total usage.
We design our systems for very easy expansion. Additional modules are fitted with an Enphase inverter and easily integrate into the existing array with just a few Zep components. No string resizing or inverter upgrade is necessary, and no extension of a racking system is needed either.
