Having the additional equipment, batteries, controllers, inverters etc. can be daunting for a home buyer.

I started looking into adding solar to a rental duplex and found out that in addition to a new electrical panels, the utility service equipment also needs to be updated.

I am sure if you have properly capitalized the LLC, have operating agreement, minutes to meetings, management contract and all other required documents, they why get separate EIN (its free after all). 90% of LLCs don’t follow the other required rules to create its separate identity, so initially opening bank account with SSN is very normal.

You may be covered for some of the equipment costs.  

We bought all equipment that cost over $2,000.00 and  prep materials and paint came out to $30.00/tub. 

If you choose to pressure wash, be sure you know how to use the equipment so it doesn't damage the wood.

A trust would be a wise move as well, if you're very concerned about your identity, but I would start by ensuring all the LLC info was buttoned up and minimize (eliminate) interaction with the tenants. 

You will need to research deeper to find out how to hold an LLC and have your identity concealed.Another option is using trusts.

it seems like a reasonable accommodation, to wear a mask, and/or boot covers or gloves or any other Personal Protective Equipment that helps provide a superior experience at my properties, over the competition.

If the other company were to fail, you could potentially acquire their employees and equipment.
