1. Solar photovoltaic system installations are increasing in Florida but the rate of installation is inhibited by the cost of these systems. The suggested research is to answer the following questions.

a. What is the average installed cost of solar photovoltaic systems on one- and two-family homes in Florida?

b. What would be the additional cost of a one- or two-family home to provide infrastructure to facilitate the future installation of a solar PV system?

i. Said infrastructure to consist of the following:

1. Structural blocking in the roof for mounting of the PV panels and equipment.

2. Mounting points through the roof membrane for mounting of PV panel racking structures.

3. A trade size 1 empty, capped raceway from the PV array location to an interconnection point at the electrical service.

4. A NEMA 3R enclosure, capable of being sealed by the electrical utility, on the supply side of the main electrical service disconnect for interconnection of the PV system. The enclosure to be labeled “For Future Solar PV System.”

c. What would be the amount of reduction in the cost of installing a solar PV system as a result of this pre-installed infrastructure?

d. How many additional solar PV systems would likely be installed as a result of installation of this pre-installed infrastructure?

e. What would be the net reduction / increase in cost of a solar PV system to the homeowner as a result of installation of the contemplated infrastructure?

2. Electric vehicle sales are increasing in Florida. These vehicles require the ability to recharge the batteries. The suggested research is intended to answer the following questions.

a. What is the average cost of installing an electric vehicle charging system in a one- or two-family home or townhouse with an attached garage?

b. What would be the additional cost of a one- or two-family home or townhouse to provide infrastructure to facilitate the future installation of an electric vehicle charging system?

i. Said infrastructure to consist of the following:

1. Provision in the main electrical panel or a properly rated subpanel of an empty space for a two-pole breaker, with sufficient capacity for a 240 volt, 40 ampere branch circuit.

2. Installation of a trade size 1 empty raceway from the electrical panel to the location of an electric vehicle charging system, terminating in an empty enclosure with a blank cover. The enclosure to be labeled “For Future EV Charging System.”

c. What would be the amount of reduction in the cost of installing an electric vehicle charging system as a result of this pre-installed infrastructure?

d. How many additional electric vehicle charging systems would likely be installed as a result of installation of this pre-installed infrastructure?

e. What would be the net reduction / increase in cost of an electric vehicle charging system to the homeowner as a result of installation of the contemplated infrastructure?
